I reload .45ACP exclusively, generally with 185 gr. LSW or 230 gr. LRN. I just realized that the last box of primers that I purchased were CCI Large Pistol MAGNUM Primers.....not Large Pistol regulars. It probably explains why the dealer had some. What would happen if I were to use these with my Hogdon HP38 load. I'm not even sure at this point as to whether they will even fit into a .45ACP Cartridge. Are they useable or should I find some soul who loads Magnums and give them to him/her? Thanks in advance.
