Thread: Drillings/combination guns

so if you had a .12ga barrel and another of a useful centrefire.....you COULD put a barrel insert in the other....in a centrefire of some sort......anything from .45/70 down to say .45apc and be legal ASLONG as its more than .222remington to comply with DOC minimum calibre levels.... the .45 long colt with say a 12'' rifled barrel would be very useful....it would be great for finishing shots,hares,possums close goats etc.
