I was just shooting with a friend, and when he unloaded his carry ammo before shooting, I asked what he was carrying. They were commercial .45acp 230gr JHP reloads from a local company. I picked up a few, and I could tell they were badly overcrimped and seemed to have more bearing surface showing than seems to work in my Glock barrels. I field stripped my 30s and showed him that they won't drop all the way into the chamber. He gave me one to take home for further analysis, and here's the stats: 1.247" OAL 0.465" crimp 5.2gr powder (not sure what it is, but I've seen it before...looks like tiny flakes of mica...maybe 231?) 229.6gr bullet 0.451" bullet diameter 0.443" bullet diameter where the case mouth/crimp dug into it 0.637" long bullet 0.011" case wall thickness at the mouth I suspect the bullets are Montana Gold, but I don't have any of their 230gr bullets for comparison. The HP cavity is very small and shallow. I really don't think these were meant to be a defense load bullet. This is the second example of ammo I've seen from this local reloader that was, IMO, grossly overcrimped. This is after a few hits in the impact puller. I thought it showed the overcrimp well.
