I had some 45LC reloads done by an outside source. I opened one box and found a couple with a dent on the side of the case. The dents are at the same place on each cartridge. Since I don't reload myself, I don't know how to "read" these dents. I presume they're from the reload process somehow because they are first time loads using new unfired brass. Can someone give me an idea whats happening here.?
