I've not had any issues with the .45ACP in any of my pistols - whether Kimber or Kahr.. I've used 230 gr RN, 200 gr HP (Hornady) and 185 gr HP... The critical part of the .45 is case length since it headspaces on the case mouth.. But function/feeding etc., has not been a problem.. (carbide dies, Dillon 550 press)..
