Hi everyone,
So this problem is perplexing me. My 1945 longbranch No4Mk1* was firing fine. Last time at the range I started to get misfires. I could tell the firing pin wasnt going in all the way from the cocking piece being a quarter inch to 1/8 " out. The primer wasnt being touched. I disassembled the bolt cleaned the firing pin and cocking piece guide, and the gun started firing normally again.
This past weekend I decided to take her out again. Fired 27 rounds no problem. Lots of rest time between firing. Then then misfires again. Light primer strikes this time, and again the cocking peice not all the way forward. Tried cocking and firing with an empty chamber twice. On the second time it went all the way forward, but I luckily decided to check the bolt face, and with the bolt cocked the face had the firing pin exposed!
Luckily I did not chamber a round, or the bolt would have blown back in my face. The peice of pin was stuck in there good. Had to bang the base of a screwdriver to get it out! Heres a pic. It was not a straight shear, there is an odd piece of metal/flake attached to the broken piece.
What could have caused this? I will be putting a replacement on there soon, but I dont want this to happen again.
P.S. I was using factory winchester ammo.
