Chill, did you know George Orndorff? He and I shot competitive pistol bullseye shooting in the early seventies. I moved from a Denver around 78 and returned to fly for Rocky Mountain Airways when BPCR shooting was taking off(no pun intended). George was really getting into that but I had another sport at that time. Fond memories indeed. Getting back into shooting at 80 years old is still fun but the body has other ideas, ha ha.
Spoke to a number of shooters that are using Ron Smiths Stainless gain twist and having very good luck. Coltsmoke comes to mind first. He is a hell of a shot and thinks they are first rate barrels.
