For the purpose of action shooting at Crumlin, Pistol Caliber Carbines (PCC) are limited to the following calibers:
- 22 rimfire
- 40 S&W
- 45 ACP
When PCC's are used in an action shooting discipline (IPSC, IDPA, Multigun) the shooter must be a minimum of 10 meters from the backstop or the berm they are shooting at. This is the same restriction that applies to handguns.
