I no longer need a shoulder buster, i bought this nice single shot to enjoy my hunting for deer. But 50% of 35 grns BP is only 17.5 grns, much of which remains in the barrel as fouling. Recoil Velocity (in feet per second): I have observed such variance with Black Powder, Black Powder Substitutes and Modern Smokeless Powder. Explanation of terms. Bullet Recoil Calculator. ITEM 8MBPE "TRAP DOOR" ACTIONS. Yes the recoil is more of a hard push than a real thump. For most cartridge / powder combinations, getting the powder charge low will cause ignition and ballistic problems. Don’t be one of them. This information is intended to be used as a reference. The most obvious is the recoil reduction that they produce. The rifle made a popping noise, reminiscent of the old, slow, black powder cartridges. 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. 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.

Black powder causes a gentle acceleration of wad and shot without a significant reduction in muzzle velocity. I have a NEF 45-70, the Factory ammo isn't all that pleasant to shoot. The muzzle was about 7 feet back from the chronograph to avoid interference from the muzzle-blast in the readings. function Recoil(form) I fill the case all the way with fffg and use a 260 grain bullet and the recoil is still much more manageable than any kind of full power smokeless. For example you can take a 30-06 ammunition and load it to 30-30 velocities without much problem. 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. It was just plain fun to shoot! If you looking for special discount you will need to searching when special time come or holidays. Start with 100 grains of Black Powder and industry approved black powder substitutes, loose powder or pellets. Low velocity, low recoil loading is possible, but as always, only with the correct reload data. I joined seeking help, n i know this has been asked many time through the yrs. Maybe all the smoke and noise is making it seem like it has more recoil. Free recoil and firearms.

I love the boom and flash and heavy recoil of black powder, but the reason always given for the heavier felt recoil seems incomplete. In other words, you simply square the velocity of recoil, which is easily calculated when we know the weight of the bullet and powder charge and its velocity when exiting from the muzzle. A comprehensive collection of interactive, online ballistics calculators! Less, faster burning powder, creating a higher peak pressure with a steeper rise and fall, results in an 8% drop in muzzle pressure and a 15% drop in pounds of recoil. 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. var bv = form.bv.value; Having said that, a .50, .54, .58 with a good load, say a .54 with 80 grains can hurt if you're not carefull. Another advantage of shooting black powder is the shot patterns, and in most cases, are more evenly spread. } The muzzle blast for the 60 and 70% loads was significantly less, and the rifle, albeit heavy, barely moved.
