Winchester's factory ammunition for the .300 Winchester Magnum is capable of 990 m/s (3,260 ft/s) with the 150-grain (9.7 g) bullet and 910 m/s (3,000 ft/s) with the 12-gram (180 gr) bullet, however old Western "Power Point" soft point can reach past 1,000 metres per second (3,400 ft/s) with 9.7 g (150 gr) projectiles. The maximum point blank ...
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy ( E t ) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f ) for non-SI units of measure.
ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains
The .300 Norma Magnum, also known as .300 NM or 300 Norma, is a centerfire magnum rifle cartridge developed by Swedish ammunition manufacturer Norma Precision.The .300 Norma Magnum uses a .338 Norma Magnum parent case necked down to .30 caliber, [1] named to differentiate it from the older .308 Norma Magnum designed in 1960, and has begun to gain popularity among long-range shooters.
The Double Tap achieves 2,825 ft/s (861 m/s) and 4,700 ft⋅lb (6,400 J) with a 270-grain Barnes TSX from a 23-inch barrel Ruger 77 African. The .375 Ruger's greater case capacity, and the "short fat" cartridge efficiency lead to increases in the neighborhood of 150 to 200 fps over the .375 H&H Magnum cartridge.
The .300 WSM also head-spaces off of the case shoulder, versus the older .300 Winchester Magnum's belted head space design. The advantage to this round is the ballistic performance is nearly identical to the .300 Winchester Magnum [ 2 ] in a lighter rifle with a shorter action burning 8 - 10% less gunpowder.
Models chambered in the magnum cartridges .338 Lapua Magnum, .300 Win Mag, and .300 PRC went on sale in 2018. [ 10 ] .338 Lapua Magnum with 1:9.375 RH twist, 26 in (66 cm) barrel, weighing 15.2 lb (6.8 kg) [ 11 ]
"Grain foot per second" (gr·ft/s) can be obtained by measuring the mass in grains (gr) (7,000 to the pound) and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1 ⁄ 1000, obtaining the power factor in kilo grain foot per second instead.
