21 SHARP – New Rimfire Cartridge from Winchester
SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) have published cartridge and chamber drawings of a new rimfire cartridge called 21 Sharp which was developed and submitted for SAAMI acceptance by Olin Winchester. While this new cartridge uses a non-heeled projectile, it has a lot of similarities with the 22 Long Rifle. Let’s take a closer look at the design of the new 21 Sharp rimfire cartridge.
