.25 Auto ammunition offers manageable recoil and a compact profile, firing a 50-grain bullet at muzzle velocities of 760–830 fps for around 100–150 ft-lbs of energy. Full metal jacket (FMJ) cartridges ensure reliable feeding and cost-effective range firing, while jacketed hollow point (JHP) rounds deliver consistent expansion and penetration for close-quarters self-defense. Brands such as Federal, Hornady and Armscor load .25 ACP rounds in a variety of bullet constructions—compare grain weights, velocity ratings and penetration specs to find the ideal .25 Auto ammo for your pocket pistol or derringer.
