I haven't had time to continue my work up loads with other bullets in my S&W 350, but I get 1760 fps with 25.0 gr of Enforcer behind a 147 gr Hornady XTP with a CCI 400 rifle primer. Recoil is not extra heavy with the weight of the pistol and light bullet. My 41 and 44 Mag handguns are considerably lighter. The S&W 350 is an X-Frame revolver. The 350 Legend was developed as a rifle cartridge primarily for use in semiautomatic rifles with case characteristics similar to 223.
