Thread: Misfires

In older rifles the firing pin spring may have lost quite a bit of its zing. It may not cause mis-fires, but but it can bugger up accuracy due to inconsistent ignition.

Its not uncommon in 22's with people thinking "my old 22 has lost its acuracy, maybe I better clean it". A bit less common in centre-fires but I had to change the spring in a Mauser Kurz I rebuilt, there were no mis-fires but the firing pin was being pushed back into the bolt, leaving very odd looking primers, and accuracy was horrible. Made and installed a new spring and both issues were resolved.
