![]() ![]() One of the most critical parts of a rifle stock as regards recoil is the comb. Lex Webernick offers it on his Rifles, Inc. An intelligent compromise is a swivel stud on the forend nose. Rifles that kick very hard are best equipped with barrel-band swivels-though when you employ a tight sling for a shot, tension on the barrel affects bullet placement. The front swivel must be far enough forward to clear your hand. Braking rifle movement with your forward hand is easiest with a pear-shaped forend that settles naturally in your partially closed palm. But while a double’s slender forend and slick barrels help you point the rifle fast, they give your hand little purchase. True, they have twice the barrel steel, and velocities and breech pressures are low. The short breech sections of doubles put the muzzles closer to your face, and their off-center bullet launch pivots the rifle. Rifle design definitely affects felt recoil, which is why one rifle can seem to baby you while another of the same weight, firing the same ammunition, kicks like an ostrich. The bullet exits faster, from a sharply bottle-necked case. 338 Winchester Magnum hurling a 225-grain spitzer 2,800 fps, mathematically speaking. 45-70 round launching a 405-grain bullet at 1,800 fps from a Ruger Number One (not a load for your trap-door Springfield!) gives you about the same blow as a. 378 Weatherby may carry a bullet only half as heavy as a 570-grain solid in the. No science behind that observation, just lots of shooting. 300 Holland are more civil than cartridges with sharp shoulders. In my experience, steeply tapered rounds like the. While case shape seems to affect recoil, sifting fact from speculation is difficult. can bump your clavicle hard enough to make you wince. 700 Nitro Express pushed me hard enough to force a step back while the barrels of the 17-pound double rose 45 degrees. ![]() Rifles chambered for cigar-size British Express rounds originally loaded with cordite are commonly considered mellow in recoil-as if those heavy bullets shuffling off at bicycle speed are too well mannered to maul your shoulder. Hiking bullet velocity exacts a high price in recoil! 300 Winchester delivers about 30.5 foot-pounds of recoil. Using these formulas, you’ll find a 180-grain bullet fired at 3,000 fps from an 8½-pound rifle in. The “7000” denominators simply convert grains to pounds. Art Alphin’s A-Square manual suggests using 5,200 fps as an average gas velocity. The formula: WV = bullet weight / 7000 x bullet velocity + powder weight / 7000 x powder gas velocity. To get rifle velocity, we must crunch some numbers. ![]() You can pencil out recoil’s kinetic energy using this formula: KE = MV2 / GC, where M is the rifle’s mass and V its velocity. Sir Isaac Newton described recoil when he determined that for every action there’s an equal and opposite reaction. Flinching moves your rifle before bullet release, so it affects point of impact. No matter how big or tough you think you are, you will react to punishing recoil. The sudden expansion of powder gas that boots a snug-fitting bullet from zero to 3,000 feet per second (2,045 mph) moves the rifle, too. How much you get and how you deal with it can make a difference on your hunt! Bullet launch is a violent event.
