Just got a JP upper with the Rock River mag block block and had the same issue, probably 2-3 per mag. I loaded up 150 rounds yesterday at 1.180 overall with a mix of hollow points and FMJ and they ran great. Not much left for a crimp on a 115. And they just barley fit in a glock mag although I did not try shooting them out of the glock. Hope it helps, good luck smitty
