BAD AMMUNITION

samysombra
I want to know where can I get information of what kind of damages could be done to a rifle just by using BAD AMMUNITION.

The problem is that a person shoot with a MAUSER 88 8X57 and he says that the barrel blow away just with 1 shot, and that the problem is the ammunition that is BAD, but the barrel blow awayarround 8 inches from the barrel end, not in the chamber.

Please help me.

    I'm just guessing here, but it sounds like there was something in the barrel.

    Sounds like a bore obstruction or shooting the wrong 8X57 ammo, see link for ammo differences.

    ok, and what kind of damages could be done to a rifle just by using BAD AMMUNITION (I mean in bad shape, as the Ammo used is from the same box he has used for some years)

    Was this the 1st round he fired or had he fired more than 1 round. If he had bad ammo the 1st round may have been stuck in barrel and the 2nd round caused the damage.

    If ammunition goes "bad" it usually does not go off.

    If the brass gets brittle then it splits a you get gas blow back into the action.

    Just about the only thing that would cause a barrel to blow like that would be an obstruction in the barrel.

    "If" on the previous shot the ammo was "bad" and allowed the bullet to not exit the barrel then the next round fired could indeed blow the barrel as described. This type of rupture is usually pretty bad, with the barrel blown back all the way to the action like the petals on a flower.

    If it was a model 88 Mauser then the bore is smaller than the 8x57 barrels "normally" encountered here in the US. However most US factory loaded ammo is deliberately loaded with soft bullets and light pressures so they will not blow up a Model 88 barrel.

    But again an "overpressure" will normally not blow a barrel several inches down the bore. They usually result in a bulged chamber or catastrophic failure of the action.

    Sounds like an obstruction in the barrel. (Mud or Bullet??) A careful examination of the barrel would probably pinpoint the culprit.

    What kind of ammunition did he use? Was it factory loaded, or did someone reload it?

    Also, was a scope recently mounted on the rifle? If so, did he remove the boresighter stud from the muzzle before he fired the rifle?

    The barrel that bursts near its end is the classic result of a bore obstruction.

    This can happen if foreign material (mud, snow, etc) gets in the barrel.

    It can also happen if a bullet becomes stuck in the barrel from a round with no gunpowder or inactivated powder (a "squib" round) and then ANOTHER normal bullet is fired after it.

    I agree; bore obstruction.

    While the 88 shouldn't have a steady diet of high power milsurp 8mm with the .323 bullet, it wouldn't cause issues near the MUZZLE.

    The damage I've seen on these from using overpressure ammo has been broken recoil lugs on the underside of the receiver and blown barrels (on some VERY early examples) within a few inches of the chamber. The latter was an issue known to the Germans who started using stepped barrels with thicker chamber ends as a result.

    Probably 'bad' translated to a dud. Primer went off and pushed a bullet into the barrel, halfway down. Powder didn't burn.

    Then guess what happened....

    It can happen either way and is sometimes related to bad ammo. A friend once had a dud leave residue in the barrel. This residue caused the next round fired to cause a bulge in the barrel.
    He was lucky with both the ammo and gun manufacturer after letters and other contacts. He was compensated by both...

    The problem is that the Commission 88 rifles have a .318 bore, the later 8mm ammo is .323. This along with the full power 8mm military ammo can explain what happened. Note some of these rifles were converted to the .323 diameter , they will have a "S" marking on the receiver.
