Super Vel Ammunition 9mm Luger 147 grain Full Metal Jacket Brass Cased Pistol Ammo 50 Rounds. FMJ load is a soft-shooting low-recoil extremely quiet alternative to full-power 9mm ball. The IPSC power factor is 132 ideal for competition. Because it is a soft-shooting load the 147 gr. Hush Puppy may not cycle suppressed pistols reliably with the factory recoil spring; a reduced-power recoil spring may be necessary.
