    Does anyone have any tested rockwell numbers for the inside of cut and button barrels? If you tested a button barrel before and after rifling would it show a marked difference? I am talking about taking a section of the chamber end, splitting it length wise and testing on the actual bore.

    Excellent reading on the making of a barrel. Thanks for posting.

    uhhhh read on mcgowens websitethey account for it!


    side note... the reason button rifle barrels hold up and last longer than cut barrels is simple. the act of pressing the button threw the barrel presses and hardens the surface of the bore.
    done right they are both accurate. done wrong and neither will shoot

    Pulling the button would have the same effect.

    Bounty Hunter,
    All button barrel makers I know contour after the barrel is rifled , because you need the same diameter steel so you have the same amount of resistance down the bore as the button is being pulled to maintain consistent bore and groove diameters from breech to muzzle. I have produced both Button barrels and cut rifled barrels so I know both processes very well.

    Load,
    I want to know how you think the bore is going to maintain it's harness after you heat treat the barrel after buttoning to remove any stress induced into the steel during the process? Plus after you are done heat treating it for stress after buttoning it also gets heat treated after contouring to remove stress induced during the contouring stage. Then you will be removing any of the surface hardness from the steel during final lapping.
