Created in 1923 by the Winchester Repeating Arms Company, the 270 Winchester Ammo was unveiled in 1925. It has stayed in production from then till the present. It has its place of origin in the United States.
The 270 Winchester Ammo is a large hunting rifle and has a high performance being suitable for big game shooting in 270 - 460 meters range, which translates to 300 - 500 yards. It has a max pressure of 65,000psi (450 MPa), a bullet diameter of 0.277 inches (7.0mm), a rim diameter of 0.473 inches (12.0mm), and neck diameter of 0.380 inches (7.8mm). In addition, its neck is 7.8mm, and its shoulder's diameter is 11.2mm. All of these contribute to a total overall length of 3.340 inches (84.8mm).
The 279 Winchester Ammo drives an 8.4-gram bullet at approximately 960mls. The manufacturer introduced two additional bullet weights much later. They were a 6.5 grams hollow point bullet for shooting vermin and a 9.7 grams bullet for shooting deer, elk, and moose.
It is amongst the most famous and widely used cartridges in the world. It has a manageable recoil, which makes it able to ensure maximum precision with every shot that gets fired. It is versatile and quite powerful. When one talks of hunting cartridges that you can fire at normal ranges, none compares significantly to the 270 Winchester Ammo. It is an accurate ammo and more than enough to adequately take down big games such as wildebeest, zebras, etc.
Over a century after Scandinavia discovered the merits of 6.5mm projectiles, the United States has finally caught on. And just perhaps, the 6.5mm Precision Rifle Cartridge (6.5 PRC) is the finest all-around one. The 6.5 PRC is a short–action magnum cartridge that pairs the exceptional aerodynamics of 0.264-inch-diameter projectiles with an efficient not-quite-overbored powder chamber. The parent case is the .375 Ruger—also basically a .300 RCM necked down to 6.5 mm. In other words, it’s a factory-produced, SAAMI-approved ballistic twin to the 6.5 SAUM and similar wildcats. Formally adopted by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) at its June 2018 meeting, we are thrilled to introduce our hand-loads for this caliber now! Velocities run neck and neck with traditional .264 Winchester Magnum speeds and are achieved courtesy of the shorter, fatter, more efficient, effective, consistent-burning powder column. Pleasant side-effects of the efficiency are less recoil, better barrel life, and good performance in 24-inch barrels.
