The .30-30 Winchester / 7.8x51mmR (officially named the .30 Winchester Center Fire or .30 WCF) cartridge was first marketed for the Winchester Model 1894 lever-action rifle in 1895. [4] The .30-30 (pronounced "thirty-thirty"), as it is most commonly known, along with the .25-35 Winchester , was offered that year as the United States' first ...
The SLAP design incorporates a polymer sabot, which allows for the use of a tungsten penetrator projectile of a lesser diameter than the original bore.By using the casing of a large cartridge with a lightweight projectile, the velocity of the projectile is greatly increased and the sectional density is improved without requiring a (potentially dangerous) increase in chamber pressure.
The .30-06 cartridge, with the 173 grains (11.2 g) bullet was called cartridge, .30, M1 ball. The .30-06 cartridge was far more powerful than the smaller Japanese 6.5×50mm Arisaka cartridge and comparable to the Japanese 7.7×58mm Arisaka. The new M1 ammunition proved to be significantly more accurate than the M1906 round. [22]
David M. Fortier and Michelle Hamilton of Firearms News magazine noted the similarity to the 1918 vintage .30-18 Auto and 7.65x20mm Long cartridge when given an opportunity to test it prior to the 30 Super Carry's official introduction. [4] Fortier pointed this out to JJ Reich, the Senior Media Relations Manager for Federal Premium.
Each of the three .30 calibre (7.62 mm) bullets weighs 150 grains (9.7 g) but the lower density frangible core requires greater volume. Powder metallurgy techniques fabricate bullets from mixtures of powdered metals such as tin , copper , zinc and tungsten compressed at room temperature to produce a high-density material.
The .30 carbine cartridge was developed by Winchester and is basically a rimless.30 caliber version of the much older .32 Winchester Self-Loading cartridge of 1906 introduced for the Winchester Model 1905 rifle. [6] (The .30 carbine's relatively straight case and round nose bullet have misled some to believe it was designed for use in pistols.)
The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. [1] [2] [3] The intention was to create an extremely accurate cartridge family for military, police, competition and specialized hunting markets that could also be easily sound suppressed.
The .360 Buckhammer cartridge offered a flatter trajectory and better terminal performance over many contemporary straight-wall cartridges while remaining compliant in most applicable states. .360 Buckhammer's parent case is the .30-30 Winchester , necked-up to use the same .358-caliber bullets as the .35 Remington and .35 Whelen .
