Had a really good year p.d. hunting this summer, main problem with my creedmore on a hot day, could only get 7or 8 rounds off and barrel was really warm.So we took a 5 gallon bucket,3 gallons of cool water in a thermas,a piece of tygon tubing and small funnel, when barrel got hot we put barrel in bucket and poured cool water down barrel, amazing how fast that cooled the barrel, back to shooting p.d.'s i'm just wondering if there's any chance of barrel warpage etc.it's a heavy pac-nor barrel.
