    Default Three groove barrel

    It seems I need more education about rifles and specifically in rifle barrels. There is a current thread running about having a barrel rebored by J.E.S. Reboring. Some are talking about having it done as a three grove barrel.

    What is the advantage to having a three groove barrel?

    My No. 4 Enfield has a 2 groove barrel. Advantage? I dunno, but she shoots straight. Three can only be better.

    Well all you need is enough rifling to impart the spin, anything more than that is just more gasses leaking by the bullet and extra cranes to store more fowling between cleanings. 3 cut rifling seems to work extremely well and is something of a bench rest shooter go-to anymore. The great ole 1903s with 4 are tack drivers shooting cast, some 03s and Enfields were just 2 wide cut groves and they seem to do as well as most 6 grove button riffled barrels.
