I received my Carbon Six 24” Howa shouldered prefit barrel a few weeks ago chambered in 308win. Screwed it onto Weatherby Vanguard (Howa) action. It’s in a McMillan Game Warden stock with a Nightforce SHV scope. Headspace measurements were spot on. The barrel looks great and shoots even better than it looks. The target picture is the five shot group shot with Hornady box ammo at a hundred yards. This was on a clean barrel. The first two fouling shots walked up, then the next three were in the same hole. This is easily going to shoot sub half inch groups. I’m so impressed with this barrel that I ordered another today for my wife’s rifle. Thank you guys for the quality barrel.
