Retired...TWICE. Triple 7 loose powder requires the least amount by weight to yield a certain velocity, and I've found it to be the softest shooting black powder substitute. If you spend any time in hunting camps, sooner or later you will hear amazing stories about the long-range performance of modern muzzleloaders. After you input the necessary data such as the bullet weight, bullet velocity, powder charge weight, and the firearm weight it will output the recoil impulse, recoil velocity, and the recoil … For example you can take a 30-06 ammunition and load it to 30-30 velocities without much problem. 2.) Bullet Recoil Calculator. Just grab a recoil pad from the market and leave the next shot of your shotgun to it. Hodgdon has three separate tabs under the DATA menu of the website’s main page to help in low recoil … Like them, it also works fine as a full-charge powder for cartridges such as the .223 Remington and .308 Winchester, but it does so well with reduced charges that it’s a top choice for making smokeless rounds for black-powder rifles. Excess black powder will just spew out the muzzle. Using this powder, the recoil goes up, and the powder now accounts for 12.1 percent of the recoil. I love the boom and flash and heavy recoil of black powder, but the reason always given for the heavier felt recoil seems incomplete. } A one-stop resource for your technical ballistic data needs. Calculate recoil from muzzle velocity and bullet, powder and rifle weight. Start with 100 grains of Black Powder and industry approved black powder substitutes, loose powder or pellets. The recoil pad for shotgun is specially made to absorb the shock while reducing back the force of the shotgun and they are pretty easy to install with the gun. I love the boom and flash and heavy recoil of black powder, but the reason always given for the heavier felt recoil seems incomplete. But then the rest of us would never draw an elk tag, so to hell with 'em! It was just plain fun to shoot! Recoil energy calculator This program calculates the recoil energy when you shoot a shotgun. Maybe all the smoke and noise is making it seem like it has more recoil. I have a NEF 45-70, the Factory ammo isn't all that pleasant to shoot. Increase the gun weight by, say, 25% and the recoil goes down by 25%. The recoil at muzzle exit is simpler to estimate correctly. Hard Cast GC @ 1,300 fps 20 Round Box. Recoil Energy Calculator. Absolutely, that 50% of the powder charge that remains unburned and is ejected with the bullet has some effect, but it cannot be all of it. The most obvious is the recoil reduction that they produce. //-->, most shotshell loads avg between 11- 47 grains of powder. var Velocity = ((bw * bv + 1.75 * bv * cw) / 7000 / W)}; The calculator above estimates the free recoil velocity at the end of recoil and also when the bullet exits the muzzle. Having said that, a .50, .54, .58 with a good load, say a .54 with 80 grains can hurt if you're not carefull. This energy is the figure most often given in books and magazines. Recoil Velocity (in feet per second): var bw =; VELOCITY FPS 245 gr. With this load, the powder accounts for 6.0 percent of the recoil. The oldtimers with their muzzleloaders would start with a patched round ball and around 50 gr. I see cast bullets from 300 gr past 500gr. Calculates the ballistic trajectory of a bullet fired from a rifle, handgun or other firearm. Do not forget that rifle weight is a crucial factor in the recoil equation, inversely proportional to recoil. BUFFALO BORE 45-70 SMOKELESS BLACK POWDER EQUIVALENT "TRAP DOOR" SUITABLE 440 gr. But 50% of 35 grns BP is only 17.5 grns, much of which remains in the barrel as fouling. (i.e. Sight in your rifle. The burning of powder is a chemical reaction. Accurate 5744 is just as versatile as the 4895s. In the shooting sports we call that reaction recoil or "kick." Free recoil and firearms. The loads described on this site were generated at the ballistics test facilities of Western Powders, Inc. in accordance with SAAMI … That gives us a very stout 18.6 ft-lbs of recoil energy from this "Airlight" pistol. var Velocity = parseInt(Velocity); _Photo by John Hafner_ Myths and misunderstandings regarding the performance and care of blackpowder rifles and propellants have cost many hunters a buck. Shotgun Recoil Calculator I shoot BP in my 45 auto in Wild Bunch matches. Volumetric Units (volumetric powder measure) 80 100 120 Weight in Grains (weighed on a scale) 56 70 84 BULLET SABOT/BULLET DIA. BTHP 80289 2960 2697 2449 2215 1993 1786 1323 1098 906 741 600 482 -1 517 0-7 -22 -454 M 223 Rem 73 gr. Endowment Life Member NRA, Life Member TSRA, Member WACA, NRA Whittington Center, BBHC, If liberals knew what they were missing, they’d give up drugs, sex and rock-n-roll for shooting and hunting. Adding 10-15 grains to the bullet (5-8% of a 200 grn bullet) would not make that much difference in felt recoil. Plug in these numbers in the recoil calculator above: 158 gr bullet, 13 gr of powder, 0.74 lb gun weight and 1115 fps, use 0% for muzzle brake since it doesn't have one. of powder and shoot in the snow while increasing the charge by five grain increments until powder started speckling the snow in front of them. Don’t be one of them. In my 44-40 revolver, for instance, Swiss FFFG feels a whole lot stiffer than Unique, even when the muzzle velocity with the same bullet is similar. Exterior Ballistics, Recoil Calculator, Wound Channel Calculator, Stopping Power Calculators (mutiple), Round Ball Weight Calculator, Powder Calculators, and more! * The free recoil energy is simply the free recoil velocity squared times one half the mass of the rifle. The powder that requires the most weight is Accurate No. — James "Mitch" Vilos aka (Pancho Vilos). } var W = form.W.value;} The powder that requires the least weight to push a 230-grain bullet to 850 fps is Bullseye with 4.9 grains. The Hornady Standard Ballistics Calculator uses BCs (G1 or G7 ballistic coefficients) to calculate trajectory and is ideal for traditional hunting and varmint bullets at close to moderate distance. { {var Total = (1 / (2 * 32.2 * W) * (bw * bv + cw * 1.75 * bv) / If you don’t achieve the desired results, go up or down in 10 grain increments and try sighting again. { It can be measured or computed empirically and has been for this recoil table. For most cartridge / powder combinations, getting the powder charge low will cause ignition and ballistic problems. var bv =; 1 1/8th ounce at 1145 fps) and the weight of your gun in pounds. If you shoot black powder or a black powder substitute, the case MUST BE COMPLETELY FULL. Chemical reactions in general are never 100%, even under lab conditions. function Recoil(form) By the way, the specific data I would like to see is related to my original question about the combustion rate of BP being faster than smokeless: surely someone out there has come across some charts or graphs of pressure over time while the bullet is in the barrel, comparing BP versus smokeless.
