The .40 S&W (10×22mm Smith & Wesson) is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson and Winchester. The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9mm size) automatic handguns. It uses 0.40-inch (10 mm) diameter bullets ranging in weight from 105 to 200 grains (6.8 to 13.0 g).

    40cal Rifle Cartridge. 10mm Projectiles Non-Rimmed.

    We have the 350 Legend cartridge that uses 9mm bullets and the 450 Bushmaster that uses 45cal bullets. Is there a rifle based cartridge that uses 40cal bullets? Maybe the 400 Corbon approach could be used with 450 Bushmaster cartridge? Edit: Just realized the 38-40 uses a 10mm bullet but it is...
