I’m not an expert on this by any means but I checked load data on 10-12 common pistol powders and didn’t see any that would give this kind of velocity from a 4.7gr charge. The company that he bought them from is pretty well known in this area and they’re a pretty small mom and pop operation so I’m sure they would have been using a commercially available powder. Does anybody have any thoughts on this? I've never used Quickload but does it have the capability of telling you what powder has the capability to give this kind of velocity in this round? Off the top of my head I was thinking that they must have loaded the ammo with the wrong powder.
