.284 Winchester
The .284 Winchester (7.21x55mmRB) is a rebated rim rifle cartridge introduced by the Winchester Repeating Arms Company in 1963. The .284 Winchester was designed to duplicate the performance of the .270 Winchester and .280 Remington cartridges from the new Winchester Model 100 autoloader and Winchester Model 88 lever-action rifles. The result was a 7 mm cartridge of comparable overall length to the .308 Winchester with greater case capacity and power potential. .284 Winchester has enjoyed a resurgence due to interest from long-range competitive shooters. Winchester has continued to produce brass cases for this cartridge since 1963. History The Savage Model 99 lever-action, Winchester Model 100 autoloader, Winchester Model 88 lever-action, and Ruger Ruger M77 rifles were chambered in the .284 Winchester. The 7.5x55 Swiss provided inspiration for the cartridge, with the bullet diameter reduced to 7mm and the rim rebated to .473” to allow for the use of the bolt fac ...

308 Winchester
The .308 Winchester is a smokeless powder Rim (firearms), rimless bottlenecked rifle Cartridge (firearms), cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar, but not identical, to the 7.62×51mm NATO cartridge. History During the 1940s, the .300 Savage became the basis for experiments on behalf of the U.S. military that resulted in the development of the 7.62×51mm NATO#Development, T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated "T65" and was similar to the .300 Savage case, but with less taper. The experimental cases were made from standard .30-06 Springfield cases which gave a little less capacity than standard .300 Savage cases because the Frankford Arsenal cases had slightly thicker walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. mi ...
