When Winchester Ammunition introduced 350 Legend ammo, it was a welcomed sight for deer hunters, especially those living in states that require they use rifles chambered for a straight-walled cartridge. Before .350 Legend ammo, they were limited to using dated, oversized, or short-range ammunition . In just a few years, .350 Legend has become known as a powerful round with very soft recoil.
Its performance is often compared to the popular .223 Remington because it’s AR-compatible when you use a .350 Legend upper. Speaking only about rifle ammo, though, the 350 Legend bullet is much bigger. With a bullet diameter of .357 inches and a 1.71-inch long shell case, the total length of the 350 Legend cartridge is 2.26 inches.
.350 Legend (9×43 mm), also called 350 LGND, is a SAAMI-standardized straight-walled hunting cartridge developed by Winchester Repeating Arms. The cartridge was designed for use in American states that have specific regulations for deer hunting with straight-walled centerfire cartridges. Winchester claims that the .350 Legend is the fastest production straight-walled hunting cartridge in the world, although some .444 Marlin and .458 Winchester Magnum loads are faster. It is designed for deer hunting out to a maximum effective range of 250 yards (230 m).The .350 Legend shares many characteristics with the .223 Remington, the overall cartridge length is 2.26 inches (57 mm) long with a rim diameter of .378 inches (9.6 mm), but it is not derived from the .223 Remington. Because of its similarities to the .223 Remington and 5.56 mm NATO, the .350 Legend is suitable for use in AR-15 type semiautomatic rifles, and will fit in most standard AR-15 magazines without modification.
Winchester has introduced many successful cartridges, including the .44-40 WCF (Winchester Center Fire), the .30 WCF (.30-30), the .50 BMG, the .270 Winchester, the .308 Winchester, the .243 Winchester, the .22 WMR (.22 Magnum), the Winchester Short Magnums (WSM), the .264 Winchester Magnum, .338 Winchester Magnum, the .458 Winchester Magnum and the .300 Winchester Magnum.
At the 2019 SHOT Show in Las Vegas, Nevada, the .350 Legend cartridge was introduced by Winchester Ammunition. The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), the U.S. firearms and ammunition industry’s technical standards-setting organization, announced the acceptance of the new cartridge and chamber standard on January 31, 2019.
