i don't know much about pistol ammo, but i traded 100 clay shooting 12ga shells for 300 rounds of 9mm. the box says Winchester (not original box), and on the side it says "Black T". the guy got them from his police friend. the bullets themselves are in styrofoam, and they have a silver steel case with a black bullet. it's got a VERY deep hollowpoint, and indentations along the rim of the point, i guess for expansion purposes. dunno about the ammo, but i figured 300 rounds of it for $15 worth of 12ga shells aint bad.
