My brother has a new Mossberg 100 ATR. It has been fired 39 times. We were shooting it this afternoon and as the bolt was being closed the gun fired. I am trying to find out from Mossberg how or why this may have happened. Any Ideas?
I sat and ran the bolt many many times and could not get it to fire like that again. I did find the the bolt was full of some type of grease. Could it get some type of forien object in the grease and allow the gun to fire.
I will check anything you guys suggest. I want to know why it did this. Any help will be greatly aprreciated.
Thanks, David.

Just smile and say nothing, let them guess how much you know.

Did you slam the round into the chamber ? Even if the firing pin was 'stuck' forward...a normal closing of the bolt probably wouldn't fire the round. This indicates that the sear caught the striker long enough to compress the mainspring...then slipped.
Obviously, the bolt was nearly locked down ?
Given that you are ABSOLUTELY sure that no finger was on the trigger...it might be a good idea to send it back to the factory.

I saw it when it happened. The guy shooting was holding the forearm with his left hand and pushed the bolt forward with the palm of his hand. Nothing hard or radical about it, just a even push and as the bolt went into the "down" postion it dropped the firing pin. If we cant find a reason for this I will have it sent back to be checked.
This is why keeping the muzzle pointed in a safe direction pays off.

If the rifle was not cleaned and oiled before shooting it leads me to think that it was a malfunction caused by packing grease and cutting oils along with metal shavings and polishing compounds messing stuff up.
Clean the gun. including the bolt is acetone or MEK. That will get all the crap out that can cause problems.
My guess is it was a fluke accident, glad nobody was hurt.
