For others, the trend of the 7mm RM losing altitude at a slower rate than the .300 Win Mag as you increase the distance is very important. Below you will find the velocity averages for the two cartridges. I believe … The old long through is just fine for me. It might be a bit of overkill for medium sized game and you might get a bit more damaged meat, but there is little doubt that it will put them down. A bullet’s design, their BC, and the muzzle velocity all influence the trajectories. Let’s take a look at the larger sample set and see how the two compare. The Roosevelt elk of Western WA tend to have smaller racks & bigger bodies than the usual Rocky Mountain elk. While there are general rules of thumb for what is required, nothing is set in stone, and as we just mentioned, there is more involved than just bullet energies. The following is a 500 yard 7mm Rem Magnum ballistic chart that was created using our free online ballistic calculator and details all aspects of the bullets trajectory from the millisecond it leaves the barrel until the time it reaches the 500 yd mark. Rifling Twist: 1:10 3. fans don’t jump in here and spoil the argument or I’ll let the 300 RUM lovers counter. The 7mm (.284-inch) bullet drops less at all ranges even though the .308-inch bullet has a more efficient, minimum drag B.C. Like most ballistic and other performance specs we have looked at between the 7mm Rem Mag vs .300 Win Mag, there is not a whole lot of difference between the two cartridges. All five of the .300 Win Mag rounds produced between 27 and 32ft.lb of energy, between 7 and 14 more ft.lb of recoil energy than the 7mm Rem Mag rounds. It's not because of the cartridge. As far as availability goes, just about every major ammunition company are loading .300 Win Mag and 7mm RM cartridges and most of them carry several different models of each. This speed along with the sectional density is going to be more than enough to penetrate to and through vital organs of big bull elk and moose at long ranges. Due to the fact that the 7mm WSM duplicates the performance of the .280 Remington while being very similar to the 7mm Remington Magnum, the reader is directed to these texts for bullet performance. When the bullet impacts the target, this kinetic energy is transferred to the surrounding tissue and organs causing massive damage. Regardless of where your allegiances are situated in this topic, hopefully you are coming into this with an open mind, because both of these magnum rounds are tremendous cartridges and their popularity and longevity in such a cutthroat field speaks in volumes to their performance. That changes the ballistics significantly in favor of the 7mm and might alter your plans. We have also included an additional 400 yard marker as there are certain hunting situations where this range can be a normal shooting distance. Let’s see if the trends continue in the same direction when we look at more rounds for both cartridges. The top two performing rounds are a 7mm Rem Mag and a .300 Win Mag option, and they only have a difference of .6″. Bullet: 7.8 mm 4. Below we have listed our ten selections to be used in this article. In a nutshell, here’s why: given equal rifle mass, optimum bullet Ballistic Coefficients and Muzzle Velocities in each caliber, the 7mm RM will shoot flatter, drift less and recoil with less brain jarring recoil than the 300 WM. 300 Remington Ultra Magnum Load Data; 7.62x51mm NATO Load Data; 8x57mm JS Mauser Load Data; 8mm-06 Load Data; 325 Winchester Short Magnum (WSM) Load Data; 8mm Remington Magnum Load Data ; 338 Federal Load Data; 338-06 A-Square Load Data; 338 Winchester Magnum Load Data; 330 Dakota Load Data; 340 Weatherby Magnum Load Data; 338 Remington Ultra Magnum Load Data; 338 Lapua Magnum … The .300 Win Mag rounds show a slightly higher sectional density than the 7mm Rem Mag rounds. The higher the BC, the better the bullet can cut through the wind, meaning it resists drag and wind drift much more efficiently than a bullet with a lower BC. This cartridge can be packed with large amounts of powder giving it a huge advantage in velocity and the ability to carry a large amount of energy over a greater distance. Complete 7mm Remington Magnum Winchester ammunition ballistics Chart. Let’s continue and see what we find. Of these, 140 grain, 150 grain, 160 grain, and 175 grain loads are by far the most common. The 7mm Rem Mag rounds have more options for higher muzzle velocities, flatter trajectories, and better BCs which helps performance greatly downrange. Discussion Starter • #1 • Mar 20, 2009. At the muzzle, the .300 Win Mag rounds have an average bullet energy of 3,640ft.lb while the 7mm Rem Mag rounds have an energy of 3,162ft.lbs. And we’re not discounting that method, it can be very valuable, but you just have to be cautious of who you are getting that information from. Mag. If your favorite round is not on the list, it’s not because we don’t think it’s a round worthy to take in the field. For a bullet to quickly kill an animal, it must reach the vital organs. Deciding which you prefer comes down to levels of recoil, downrange energy, bullet drop and bullet drift, none of which are significant unless you plan to be throwing at targets beyond 500 yards. The difference between the highest .300 Win Mag and the lowest 7mm Rem Mag round is even more drastic with a difference of 615ft.lb of force. Personally I MUCH favor the 7mm Mag over the 300 WSM. If you think 150 f-p impact energy will spell the difference between venison on the pole and a lost cripple, you might be interested in a bridge I’m selling in Manhattan. We do see that the Barnes .300 WM round is a big boost to the averages and without it, the average performance between these cartridges would be much similar. Each cartridge is today the most popular magnum in its caliber, raising the question: Which is the best all round hunting cartridge? We think the 168gr bullet is a great weight for hunting purposes as it has a manageable recoil. Both have been popular from their inceptions. While this cartridge has been and is still used in sharp shooting corners of the military, the majority of its action is found in the hunting world. Let’s step out and take a look at the trajectories of the 7mm Rem Mag vs .300 Win Mag at increased distances (Graph 6). Both are very capable and popular cartridges and both pack a good punch. The recoil energy for these rounds was generated as we described earlier and used the same variables. 15.64 fps 30.4 foot-pounds. For two cartridges that overlap in so many applications, it is easy to get on the path of trying to determine which cartridge is better. In our opinion, it can’t be denied that this cartridge can fill several hunting needs and is the reason for its continued existence and in our opinion, one of the best magnum rounds of its caliber class. Stopping or knockdown power as some like to call it is going to be more important to those looking to utilize these cartridges for hunting purposes. Weight is only a part of B.C. While the .300 Win Mag overall has higher bullet energy, the differences are not too extreme. It is also important to keep the sectional density in mind when looking at momentum. For instance, the vast majority of 7mm Rem Mag factory loads shoot bullets in the 139-175 grain range. While hand loading and the art of balancing the various components that go into a cartridge is a topic worth discussing, it is beyond the scope of this article. This way, you can have more data at your disposal if you are looking to make a decision, and it will also check our small sample group and help us confirm that the results we are seeing is accurate for the cartridges as a whole. vs. .300 Win. The second metric that we will use to get an idea of how these two cartridges compare in potential penetration is the momentum of the bullets. Survival. (Or read this article for another take on magnums.). As we move out the 300-yard mark, there is a little more spread between the rounds but still no clear cut advantage for one cartridge over the other. vs. .28 Nosler vs. 7mm RUM. Does the perfect muley cartridge really exist? And, this is of course omitting the type of bullet that is being fired which in the field, is going to have to be taken into consideration. Both of these rounds produce enough KE to create a lot of damage on the largest North American game at all ranges most hunting shots are taken. And though it is fine for looking at now, when making your final decision on a specific round, it is important that you take into account all of the factors. And like earlier, as the rounds move downrange, the gap between the two did shrink. What we are saying is that the differences in performance shown here will translate to differences in performance for you when using the same firearms chambered for each cartridge, so the comparisons made here are still valid. UMC Handgun; Hog Hammer Handgun; HTP Copper Handgun; Subsonic; Performance WheelGun; High Terminal Performance (HTP) Ultimate Defense Compact Handgun Loads While you need a certain amount of velocity to get the proper terminal ballistics, there is a fine line between too little and too much velocity. entsprechend lange/schwere bleifreie), so kann es sein, daß diese nicht mehr präzise fliegen. With that in mind, let’s bring in a more diverse selection of rounds for each cartridge and see if we still see similar trajectories. If you look around the internet long, you will find that there are circles of devout followers and also unbelievers in the .300 Win Mag for various reasons. The heavier, larger caliber bullet delivers more energy at all ranges despite starting with a slower MV. The 7mm is a belted cartridge and the 300wsm is a rimmed cartridge. We have graphed the bullet momentum of our ten rounds and graphed them below (Graph 9). In my opinion both the SAUM and WSM … Instead, your advantage is going to be achieved by selecting from individual rounds and both the .300 WM and the 7mm RM have rounds with phenomenal trajectories. Still, it is accepted that 1,000ft.lb of energy is a good mark for deer while 1,500ft.lb is more suitable for elk. In this section, we are going to look at the sectional density (SD), which is a number calculated from the caliber of the bullet, as well as its weight. The following ammunition cartridge ballistics information and chart can be used to approximately compare .300 WSM Winchester Short Magnum vs 7mm-08 Remington ammo rounds. With the larger sample size, we see the same trend that we saw above. November 25, 2019. And when we say spread out we are still looking at a range of less than 2.5”. As long as you keep those variables constant from round to round, the trends we see are going to remain the same. The cartridge is also able to be to take a variety of bullet weights. We’re don’t mean to insult anyone’s intelligence, and we are probably speaking to the choir here, but a bullet’s flight path is not a straight line but rather a parabolic shape. Given that, I would happily and eagerly hunt anything with either cartridge — even charging brown bears. The 175 grain bullet worked well on Elk and caribou for me. The 300 win mag … Tomahawks Are Back: These American Relics Have Seen a Resurgence in Military and Survival Situations. We have also provided the average tables throughout the article below to make it a little easier for you as we move through this section. We have kept some of these variables as constants to better compare the two cartridges. And for hunting purposes, we are not sure that an extra .300 ft.lb of force is going to make much of a difference. After we have examined these sections, we should have a much clearer understanding of where these cartridges excel and where they fall short and will let us begin teasing apart applications one cartridge might be favored over the other. Best 9mm Ammo 2019 [Self-Defense & Target], 6.5 Creedmoor vs .243 Win – Cartridge Comparison, Best .40 S&W Ammo: Self Defense & Target Practice. To do this, we have selected five popular rounds from each cartridge that include several different bullet weights and intended applications. We also hope that you have come to the same conclusion as we have after researching these two cartridges. Though the averages give a slight advantage to the 7mm Rem Mag in flat trajectories, especially as it moves out to the 600 and 700 yards range, the two top performing rounds at each yardage marker was a 7mm RM and a .300 WM. G1 Ballistic Coefficient Must be between 0.001 and 1.0. Well, I wouldn’t be. The ballistic coefficient is derived from an equation that includes input variables from specific cartridge specifications including bullet dimensions and velocity. Mule Deer Cartridge Showdown: .270 Win. Both cartridges have their rounds with heavier bullets and subsequent higher SDs. More expansion causes a larger wound and also transfers the energy carried by the bullet more efficiently. In the simplest explanation possible, the ballistic coefficient gives you an idea of how well a bullet is streamlined and how well it can overcome air resistance. of this 210-grain .308 bullet helps it resist air drag, enabling it to retain more of the energy it started out with. The following ammunition cartridge ballistics information and chart can be used to approximately compare .270 WSM Winchester Short Magnum vs .300 Winchester Magnum ammo rounds. Obviously, there is no real difference in the BCs of these two cartridges. You can definitely save a few cents per round by looking into handloading for both of these cartridges. Before we list some these differences between the averages of the two cartridges, it’s important to keep in mind the applications you plan to use one or both cartridges for. Tomahawks Are Back: These American Relics Have Seen a Resurgence in Military and Survival Situations . However, the.300 Winchester Magnum generally uses heavier bullets than the 7mm Remington Magnum. The first thing that jumped out at us as we looked at this data is that unlike the recoil, there is not a cartridge that has an overall greater amount of velocity. So as you can see, these numbers are pretty fluid and can fluctuate depending on a variety of factors. Neck: 8.0mm 5. 300 Remington Ultra Magnum Load Data; 7.62x51mm NATO Load Data; 8x57mm JS Mauser Load Data; 8mm-06 Load Data; 325 Winchester Short Magnum (WSM) Load Data; 8mm Remington Magnum Load Data ; 338 Federal Load Data; 338-06 A-Square Load Data; 338 Winchester Magnum Load Data; 330 Dakota Load Data; 340 Weatherby Magnum Load Data; 338 Remington Ultra Magnum Load Data; 338 Lapua Magnum … Just because it can be done does not mean it makes sense, despite what you might read in advertising copy. There are several factors that influence the amount of penetration that is going to occur, other than the type of animal. Since these two cartridges were nearly identical in their BC’s, let’s see if the same trend continues when you look at the short and long range trajectories. From what we are looking at from these factory loads, velocity is definitely a wash between the 7mm Rem Mag vs .300 Win Mag, but that might not be the case when we bring in more data. The .300 Norma Magnum is also another cartridge which offers some excellent long-range ballistics, and has grabbed the attention of the U.S. Army. Mag. And for hunters, where you might not have all the time in the world to take a shot, the fewer variables you have to account for the better. That’s the year Winchester brought to market its now famous 300 Winchester Magnum. And you can’t discount the role recoil can play in accuracy. If you are planning to shoot factory ammunition only, check back here for Part Two of this cartridge comparison blog. The velocity is an interesting and critical performance spec for any cartridge comparison. Both are chambered in just about every hunting rifle made, including wonderfully affordable models like. The 300 WSM will have more recoil than you presently have, but put on a Vais muzzle brake and recoil will … Those are always the deciding factors: right bullet, right place. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. We are looking at the bullet drop (inches) from the 50 to 300 yards with the firearm zeroed in at 100 yards. By Ron Spomer. In this next section, we are going to look at several sub-categories of stopping power. You will find these tables at the end of each section throughout the article. Neck: 8.6mm 5. The higher B.C. Is the 300 PRC unique enough to establish itself? We have compiled the G1(for comparison of all bullet types) ballistic coefficients for each of the ten rounds and listed them here (Graph 3). Best Concealed Carry Insurance [Comparison Chart], If you’re looking at a cartridge comparison, you are going to end up looking at the ballistic categories. With practice, either one can easily become your go to round. Base: 13.0 mm .30-06 Springfield (7.62×63mm) 1.

Closing Comments The 7mm WSM will likely remain popular for many years due to its ability to be housed in short, lightweight rifles. Both are chambered in just about every hunting rifle made, including wonderfully affordable models like Mossberg's Patriot as demonstrated here. A maximum bullet rise of 1.5 inches is appropriate for shooting small animals, as they present a small target, particularly if head shots are necessary. By doing this, you as a reader has a better resource and source of knowledge to make your own decision. What is interesting is that as these rounds move downrange, the gap between the two cartridges begins to close. Factory load options might change your mind. The majority of bullet weights used for the 7mm rem mag rounds for hunting purposes fall between 150 and 180gr though there are outliers of lighter and heavier bullets. In ballistics catalogs the point of maximum bullet rise is often called the mid-range trajectory, or sometimes the maximum ordinate. At the 200 yard mark, all ten of these rounds are clustered very tightly with a difference of only .7” between the flattest and steepest round. If you were of the mind to get as much penetration as possible, the numbers say the .300 WM is better suited. While we will not be graphing all of these rounds (that would be a nightmare for your eyes) we have calculated averages for both and will present those at the end of each section. From this graph, it is easy to see that these two cartridges show very similar trajectories out to 500 yards. We hope that this cartridge comparison of the 7mm Rem Mag vs .300 Win Mag has given you an unbiased look at some of the ballistic and other performance properties of these two rounds. The 7mm WSM d… That changes the ballistics significantly in favor of the 7mm and might alter your plans. That kinetic energy is only one factor of a rounds stopping power, but it is an important one. As you can imagine, this makes the BC a relevant piece of information for both long range competition shooters and hunters alike. THE BEST GUN DEALS AND HANDPICKED GEAR RECOMMENDATIONS, Subscribe to our Newsletter and we send you the best deals right into your inbox. This transfer is also affected by how the bullet reacts on impact, such as how the bullet expands. Base: 12.0 mm From the first look, there are no significant differences between 7mm Remington Magnum and .30-06 Springfield when it comes to profile. And like we have mentioned before, using a proper bullet and putting it in the right spot can make up for lack of energy. And if you’re a person who enjoys burning through a box or two at the range, that extra 10ft.lb of recoil can be fatiguing and lead to a decrease in accuracy over time. When you know when these effects start occurring, you can adjust accordingly or go with a round that might give you more flight time at these speeds. With two cartridges that have the potential and the reputation for long range shooting, we wanted to also look at how long these cartridges can stay in supersonic flight. I went back to the .308 until I went to Africa again in late 90s and then 2004. in 99 I took a .300 Weatherby and a .375 Weatherby. Because of this, it will be interesting to see how these two cartridges stack up in various performance categories. We are interested in how long these rounds can maintain supersonic flight because it influences the calculations you will have to make to be accurate with long range shots. Cartridge Type: Rifle Height: 2.1" Width: 0.535" Average FPS: 3134 Average Energy: 3314 Average Gr: 152 Recoil: 2.06 Power Rank: 4.76 of 20 The 7mm Winchester Short Magnum (WSM) was designed in 2001 by Winchester Repeating Arms Company and Browning Arms Company. We can do the same exercise, but instead look how the weight of the bullet affects the SD. Understanding your bullet design, how it expands, and the velocity needed for proper expansion and penetration is a huge can be the difference between a clean kill or an injured animal you have to track through the night. These results shouldn’t be too surprising. We think which cartridge has the better accuracy comes down to the person pulling the trigger and their level of experience shooting said cartridge. Higher BC rounds tend to have flatter trajectories. fans don’t jump in here and spoil the argument or I’ll let the 300 RUM lovers counter. It is also available in a wide array of bullet styles which gives it a lot of versatility. Meaning, how well can the object, a bullet in this case, overcome resistance and keep moving forward. Most weights are within the 150-200 grain range, but there are several lighter and heavier rounds available. We will look at several ballistic categories as well as other performance specs throughout the article, and we hope that in the end, you come away with information for a more educated decision based on your hunting and shooting needs. The 7mm Rem Mag has become over recent years, one of the most popular magnum rounds on the market for hunting purposes. The higher the sectional density, the less resistance the bullet encounters because of the smaller area that is interacting with the target. With a degree in Microbiology and several years of doctoral work manipulating bacterial genes, he attempts to merge the rational and unbiased thinking of scientific research with the passions of hunting and fishing. It is important to make clear that we are looking at recoil energy and not the actual kick or felt recoil, though increased recoil energy for one round over another will often translate to increased felt recoil of the same round. Now, you 300 Weatherby Mag. The physics and math behind the ballistic coefficient and its implications, while interesting, is not something we are going to attempt to convey in this article, but we do urge you to check it out. By the time they reach the 500-yard mark, that difference is nearly cut in half to 224.4ft.lb of difference. There are 7mm Rm rounds that outperform some .300 Win Mag and vice versa. With two bullets, each with a .300” diameter with one weighing 100gr and the second 150gr, the 150gr is going to have a higher sectional density and deeper penetration. Most brands offer 170 to 175-grain options in 7mm RM. Ballistics comparison video between the 7mm Remington Magnum vs the 300 Winchester Magnum. While the three .300 Win Mag rounds maintain their lead; the other two are tightly clustered with several 7mm Rem Mag rounds. Moment is simply how well an object in motion will stay in motion. 7mm Magnum Showdown: 7mm Rem. With these two cartridges, we see fairly similar limits for supersonic flight though the 7mm RM rounds have, on average, 36 more yards of supersonic speed. We also do not see any trend towards one cartridge having a flatter trajectory than the other. You really are comparing apples and oranges. Bullet: 7.2mm 4. And recoil does play a role in choosing a cartridge, especially if you are dealing with a decision on cartridges that can be used for similar applications. In this case, the 7mm Rem Mag shows slightly less bullet drop than the .300 Win Mag round and even at their most distinguishable range, we are only looking at around 5” difference. It has a rebated rim, bottleneck casing with a 1:9.5 twist on a large rifle magnum primer. Now, 100fps for some might be a bigger deal than others, but keep in mind it’s only an average. In fact, we don’t think there is a big enough difference in these categories to make you lean one way or the other regarding accuracy from the data we have looked at here. Mag., the new .28 Nosler, and the over-the-top 7mm RUM—a shoot-off to find the best. Latest. Overall, both rounds are really overkill for these game animals stopping power wise, but that extra range can be a game changer. Temperature (°F) Maximum 140°F; Minimum -40°F. Firearm Setup. For long range precision shooting, both of these rounds have options to get the job done. By Ron Spomer. used the 7mm alot from the 80s and for me it was a pretty hard kicker not much less than a .300 Win Mag. It will a produce a line graph showing the bullet drop and flight path of the bullet. And if you need some extra power at short range the differences are nowhere enough to make you decide against the .300 Win Mag. For the sake of clarity and brevity, we decided on only five selections each. While some of you might have no interest in the history of either of these rounds, we not only think it is interesting, but we think that if you have an idea of why these cartridges were designed and produced gives you a better understanding of their intended uses. Get our PDF with 13 pistol & rifle targets (worth $48) including expert instructions for FREE! Like the smaller sample set and like the averages we saw when examining the short range trajectory, there is not a whole lot of difference between these cartridges. The case and overall length of the .300 Win Mag are slightly longer than the 7mm RM, and its overall case capacity has a larger volume. Right from the muzzle, the lowest .300 Win Mag round is carrying 3,474ft.lb of force while the highest 7mm Rem Mag round is carrying 3,303ft.lb of force.
