Check to see that there is nothing in the trigger housing group. Sounds like maybe an old primer is stopping the hammer from going all the way to the back of the firing pin.

bar misfire

well, i thought that also, so with the gun reassembled minus the bolt dust cover i watch the hammer drop and everything seemed like it was functioning properly. the only thing i can figure is either the bolt is messed up or the firing pin is to short. new bolt $150 through numrich and another $40 for a new firing pin. this gun was completely and totally clogged when i got my hands on it! buffer in a half dozen pieces well you can prolly imagine....lol. Anyways ive gone through it and replaced all parts that i knew were bad but cannot justify spending a couple bennys on it if im not sure. I appreciate your response though for sure!

Disassemble the bolt and clean the firing pin channel. My guess is there are brass shavings or dirt blocking free movement of the firing pin.

BAR

I'd get ahold of Browning and find out what the firing pin length should be vs what you have . There's a buffer spring in the bolt that could be full of crud , and not compressing all the way . Your problem is in the bolt for sure ! Aren't they fun to put the buttstock back onto ?

Not saying this is what you did, but a while back I took in a Rem 700 in 7 Mag that the customer said would not fire. Checked it out, no problems. Customer sent it back with the same complaint. I made him send me some of his ammo. Guess what? 7x57. Problem solved. Goatwhiskers

Firing pins don't "wear". Either the bolt is not going into battery, or the firing pin is somehow jammed inside the bolt. It has been a long time since I have had a BAT apart, but if you remove the pin holding the firing pin in place and inspect the pin and the bolt, you may find your problem.

Or just sent the gun to Browning for repairs, they will fix it without switching out all the internals parts one at a time.
