    Shooting an original Winchester M1 carbine but after 7 rounds, it ceased to fire. Examined the primers of the rounds that did not go off, and they had only a very light--just a touch--of mark where the firing pin hit. The firing pin "seems" to be okay (but I have not taken the bolt apart). Have ordered another pin but could there be another problem that I'm missing?

    Hairy,
    As long as the hammer is falling correctly and the bolt is in battery, the only other option is foreign matter in the bolt or a broken pin.

    Need to strip and clean the bolt.

    Hairy, I'd try to borrow another carbine & temporarily "swap out" the trigger group & bolt to see if you can pin down the problem to one of those.

    If the problem is in the bolt, I suggest that you pay a professional to look at it. It is difficult to re-assemble without a special tool.

    What ammo are you using? Some of the ex-combloc ammo will have "hard" primers.

    Hairy... As already mentioned, it could be a broken firing pin.

    Another cause may be the ammo. If you are shooting reloaded ammo, the cases may be too long. When resizing carbine brass it stretches slightly, and if not trimmed to proper length it will cause the bolt to not quite close all the way into battery. When this happens, it will many times cause a light strike on the primer. Since this round headspaces on the front edge of the case this is very critical.

    If you are shooting new factory ammo, then I would guess its the firing pin.

    I had the same problem with my Inland once. I had loaded the ammo to the correct OAL, but the shoulder of the bullet had a steeper angle and contacted the rifling to soon. It looked as though the bolt was in battery, but wasn't quite. Mark a couple bullets with a magic marker and see if the ink is disturbed when cycled through the action.

    Thanks, guys, for the valuable info. Since I don't have any spare parts for the carbine, I ordered them and they are enroute.

    The ammo was purchased recently (not old stock).

    As I mentioned, the first 7 rounds have a centered, sufficient hit on the primer; the next 3 have only a slight mark that let me know the pin hit--but VERY lightly. I suspect it is the firing pin but will find out.

    Thanks again.
