Protrding Primers with Winchester 1894

glabray
I have several pre-war 1894s in 30-30 caliber and when fired the primer alway protrudes several thousanths from the head of the case. The effect is much like a squib load in a revolver. If it is due to excess head space I'd think there would be enough pressure in a 30-30 round to back out the whole case not just the primer. My 94s in 38-55 do not do this. Any suggestions as to the cause?

    glabray...

    Are you using factory loaded 30-30 ammo, or your own handloads[?] Ordinarily, I would jump all over what you are describing as being a headspacing problem... but if it is doing the same thing on several different rifles, the ammo has to be the suspect.

    The reason that the entire case doesn't move versus the primer, is because it has a MUCH larger friction/sealing surface area than does the primer.

    My other thought on this, is that if you are shooting reloads, the primer pockets may be slightly oversized from repeated loading/cleaning. The 38-55 is a very low pressure cartridge, and it is unlikey to push the primer out even if the headspace is out of tolerance a bit.

    yes this is caused by ++headspace, is this a magor problem?.. no, .30/30's do this on a regular basis. .30/30's headspace on the rim, you cann't get excessive headspace by over resizing one like you can with a rimless cartridge. with a cartridge in this pressure class it is someting to watch but if it's only backing the primers out <.015" I would still shoot them
