    Default What's the cause of this?

    Any idea as to what caused the damage to these?
    32 S&W Long, brand new Winchester ammo
    Rollie has been cleaned and functions 100%

    Are those two pieces of one case which was blown apart, or the bent mouths of two different cases?

    My suggestion would be to use ammo other that Winchester and see if the problem persists.
    I suspect a bad batch of Winchester ammo.

    It is 2 individual cases, with a small piece missing at the mouth of each. (small like a nail clipping)
    No further damage or cracks and primers are still intact.
    I also suspect a bad batch, there was another case that was a bit out of shape, slightly dented,
    and another one that had a small chip of the rim missing.

    Were the bullets seated correctly? I assume these came with lead bullets. When loading lead, and if the case mouth is not belled enough, it is easy for the case mouth to be folded inwards by the bullet. When fired, it folds out again, and could even snap off. Just a guess, there could be many other possibilities. Winchester brass is not high on my quality ranking, especially in the handgun calibers.

    Inspect the rest of the ammo before firing and see what these correlate with.

    Ive only seen damage like this when over sized bullet or bullet seated skew does this damage during reloading

    Maybe I am stupid, but I do not catch on whether this occurred during loading weapon, reloading or when shooting it? A clear statement of what happened.
    If when shooting,then the case is not clear of chamber when slide is coming back to pick up next round.

    Back off the crimp. Repeated over crimp on the same spot is thnning the case mouth. When the bullet goes, it takes the edge of the crimped mouth with it.

    It's a small cartridge, it doesn't need any crimp at all.

    Correction - didn't see that it was factory ammo. Then it's over crimped at the factory and the brass is too hard.

    Revolver, so definitely noot due to loading or unloading. Factory ammo si I think it is defective brass that cracked when crimped and which the tore off on firing.
