I've reloading for many years, recently I discovered that my reloads for the .45ACP that work perfect in Colts 1911 S&W 1911 or Kimber, will not work on HK .45, Shield .45, Sig 220 or any newly manufacture .45 ACP gun, by not working I mean the guns is out of battery load will not go fully in. Apparently these new guns have tighter chambers, or my reloading dies are worn out ? LOL any suggestions of a re-sizing die that is tighter ?
thanks C S
