Thread: Cold Bore First Shot

Yeah I reckon it's more 'clean' bore that is the issue. I dry boresnake too if I'll be hunting with that rifle regularly. I used to put a shot into the ground as I left the vehicle if my barrel was clean and I was going to to be headshooting, if bush hunting or body shooting I didn't bother.
Some rifles with overbarrel suppressors can suffer more from cold bore if the rear bush is too tight/uneven close clearance to the barrel. More bush clearance will fix this.
