Underwood +P
Has anyone fired Underwood +P 40 cal ammo? Another shooter let me shoot 10 rounds they sound and recoil more than a 45acp I never had hand sting shooting my 40 reloads at higher than starting recommendations . What gives them that much power? The box said 1500fps, are they just using a higher load? I cant remember what the head stamp was but it was an unusual brand marking.
