I haven't reloaded .45 ACP in about 40 years, yes, I'm an old fart. Today while helping brother in law break in his new Gold Cup (shoots like a freakin rifle) I noticed the factory loads we were shooting had diferent size primers. As I stared in disbelief, I thought it was some major malfunction. The Federal Champion 230 gr RN hard ball had small primers and the Winchester white box 230 RN and the Remington 230 RN, cheap stuff had large primers. What happened in the last 40 years???!!! What do I do buy Small PP for some and Large PP for others???? Somebody SPLAIN please
