    Have you/are you shooting steel cased ammunition?
    The difference between a Socialist and a Communist is that the Socialist doesn't have all the guns yet.

    There's your problem! Now you know why its so inexpensive. It causes feeding and extraction problems.

    Steel cased cartridges were invented primarily to keep gunsmiths in business.

    When you fire a brass cased cartridge, the case swells up against the sides of the chamber. But when the pressure subsides, the case shrinks back, to a degree, allowing it to break free from the chamber walls.

    But with steel, the case can swell against the sides of the chamber and stay that way. And if the case is lacquer coated, as most are, its essentially glued in place. Usually you see it when the gun has been shot for a while and is hot. And it depends on the steel in the case, its hardness and such. It varies from maker to maker, batch to batch, and even bullet to bullet. Which is why you can shoot 500 rounds through the gun without a problem and then have #501 suddenly seize.

    I saw an AK once that had one stuck in the chamber so tight that I had to put a wooden rod down the barrel and knock it out with a sledge. And even if this doesn't happen to you and you get away with firing steel cased ammo. It's hell on the gun. The extractor has to work real hard to get the cases out of the chamber. Broken/worn extractors are common on guns shooting steel cased ammo. And it doesn't do the chamber any good either.

    And many of the low cost, steel cased rounds coming out of places like Russia, use steel core bullets rather than lead. Really hard on the barrel.

    Like I said, steel cased ammo exists primarily to keep gunsmiths in business. Nothing but trouble.

    i was under the impression that the ruger mini 14 was a reliable gun..gunsmith is still saying it was probably the round that did it..i looked the the ammo it is remington umc 55 gr. and its brass cased not steel.

    Remington UMC ammunition is not the best there is.
    I would guess an overlength case or shallow seated bullet.
    Ruger does not say anything about steel cases ,but they do not recommend reloads in the Mini14
