    I'm wanting a bolt action for the 7.62x39. Reason is not part of the question. Have found a few: CZ, FN, Ruger, Remington and even a Enfield conversion. My question is: I heard that some manufacturers are using a .308 barrel instead of a .311 and could be over pressured by surplus fmj 7.62x39 rounds. Anyone heard of this? Thanks.

    FIRST OFF

    None of the manufacturers you list use a .308" bore. In fact the ONLY production 7.62x39's that used a .308 bore were the very first run of ruger mini30's


    SECOND

    even If you had a x39 made with a .308" bore the .002" diffrence is NOT enough to cause any pressure problems whatsoever. And yes I have such a rifle

    Welcome to THR

    I believe Ruger still uses the .308 bore. The new Lyman 49th edition handbook agrees with this.

    I have seen books be wrong before but I don't have a slug to prove otherwise.

    Yes krochus I know you know a lot about the x39.

    See, I knew you knew somebody that slugged one. It's one of the reasons I'm gonna slug mine one of these days.

    As we all know, all results will vary. Just makes a person wonder why the book does have a disclaimer in it about that and it's not true for all of them.

    because it is a lot harder to over-pressure a 311 bore w/ 308 bullets than it is the other way around... they're just covering bases.
