    Hi everyone,

    I had a significant number of tulammo rounds fail to fire. Out of a box of 20 I had 5 failures.

    This I know is very cheap ammo, however I would like to know if there are any other things I should be looking at with the firing pin. This is my fathers rifle and really has not been fired much.

    I'll be shooting some wolf steel cased this weekend and I hope it will be more reliable.

    Any thoughts or suggestions would be appreciated!

    My thoughts...

    Did you save the shells?
    Is the strike mark the same for the non fires?
    Have you tried them in another rifle?
    Saw this recently when sighting in for a pig hunt. 1 out of 4 misses in a buddy's rifle, but fired fine with mine...he is looking for a replacement pin.

    No I did not save the shells. I was able to re-cock and try firing the round a 2nd time. Each fired properly upon second attempt.

    I did look at the shell after the that and it seemed fine (as it should have).

    I would stay away from the steel casing ammo. It causes ejectors to break. Be careful.

    In all likelihood, your firing pin spring was not engineered for the thick hard primer cups of military ammo.

    There's nothing wrong with either your rifle or the ammo. They just aren't a match. If you wish to take advantage of the low cost Tulammo for practice, a slightly heavier spring would solve the problem.

    Another option is to try Wolf, Silver Bear etc. they might work fine in your weapon.

    And from my experience with a great quantity of steel cases ammo, I must respectfully disagree with the post about steel case breaking extractors.

    I've used a ton of it in several different weapos with no ill effects.
