WASR keyholing

    I have a WASR which I was fairly pleased with. Shot awful with wolf, but I got some Yugo stuff and it was doing well with it. Then I noticed the holes in the paper were huge. Fairly certain it is keyholing; I know what a 7.62 hole looks like and these are oblong, and as nice as having a 14mm hole is, I think there are other problems...

    If you're going to say "that's what you get for getting a Century WASR", I really don't care. That's not the point.

    Any thoughts as to what is causing it, or how does one fix it?

    Put a hard backer behind the paper target.

    If the paper is free hanging it will try to get out of the way and the holes will not be perfectly round.

    Pull off the muzzle break and have a look at the crown of the barrel. A damaged crown could be the culprit. Also, take a look at the muzzle break itself. You shouldn't see any copper strikes. If so, that's no bueno.

    What's the bore and throat look like? It takes work to shoot out a 7.62x39 barrel, but the throat will go eventually. BSW

    I'm betting on rcmodel's solution.

    What's the history of your WASR?

    Is it a Century? Or was it assembled by someone in their garage? Is it from an old parts kit that still had the original barrel?

    What is the rifle twist on your barrel and the bullet weight you fire? Maybe you just need to match both and key holing will stop.

    If the bullets are in fact "keyholing," i.e., from lack of rifling stabilization, I would think it would be grossly inaccurate with any and all ammo. I suggest firing into a piece of white cardboard with a rigid mounting instead of the tissue-like paper that targets are typically made of.

    Maybe the bullets are hitting the ground just in front of the target ,?

    OK the rifle is a century, per the OP.

    I checked the muzzle brake, and it's loose. How do I tighten it?

    Oh and there are copper colorings in the muzzle brake as well, another point for that theory.
