    OK so here is what i have
    I used a Bushmaster Ar-15
    [​IMG]
    [​IMG]
    the ammo tested was US military surplus(2 rounds green tips on right) and some UK military surplus (1 round unknown manufacturer)
    [​IMG]
    the rounds were fed into the magazine and each one was loaded into the weapon from the open bolt position.
    [​IMG]

    Here are the results:
    this is after 10 open bolt slams.

    As you can see the face of the primer is definitely dimpled.
    However the dimple appears to me no deeper than 1/32 of an inch. I don't have any fired brass from my weapon, and i didn't want to shoot anything off in my backyard so i don't have anything to compare against.
    After the first slam, the was a slight dimple, barley noticeable. After 2-3 more the dimple rounded out and became a little larger in diameter, however it did not get any deeper.

    So my conclusion is, a slam fire from a M-16 type weapon would be an extremely rare occurrence with a shell that was never loaded into the weapon.
    Even after 10 loads with the same shell, no slam fire occurred, so i believe this to be a unfounded rumor, or a freak occurrence.

    We had a conversation at the department yesterday about this. Guy slammed home a round in his Mini-14 and freaked out over the dimple. Had to 'splain to the guy that it's normal and that it's normal for the AR's also................

    Do AR's and Mini-14's have floating pins as well? Guess I just don't have the cajones to slam my bolt actions hard enough. :haha:
