I have no experience to compare my colerain barrel with except a Pedersoli.... Both will make a single large hole wth 3 shots from the bench at 25 yds, inside 3" at 50 yds. I took a deer on opening day with my brand new colerain 44" .54 at 165 paces shooting offhand... The barrel seems to be at least as accurate as I am. Don't know what standard you ae looking for, but I can't imagine needing anything more accurate........ I like their profiles and availability. I have heard of some guys having problems wih Colerain breechs etc. b t have had no poblems in my limitd experience.
