    The Angle Leading Into The Rifling

    In shooting paper patched have you developed a preference on the angle leading into the rifling?

    Well, I have a few rifles with throats that have worn into a taper that allows for the full support of the exposed section of the boolit in the taper. I'm talking fairly long boolits. One of those rifles shot very well even though the muzzle end of the barrel looked worn. Actually, the whole bore is worn but the end section looks more worn.

    An advantage of such a worn throat is that the boolit takes on a simple taper (with only the seating section being parallel which can be ignored) which makes for a simple taper patch design with associated ease of rolling on the patch.

    Starting out with the chamber having the extremely shallow angle is what's on my mind.
    Buying a reamer and a new barrel, well, may as well do it up right.
