Picked up another nice 1916 in 7mm. Head space checked out fine. Went to test it out and it snaps, but doesn't fire. Of 5 rounds, there was no mark whatsoever on the primer.
Came home and took the bolt apart. Firing pin measured in spec. Spring not broken. Did a "redneck" test on it. Having no snap cap, I took 3 spent shells, applied auto scratch putty over the ends, let them dry, and sanded them down. Screwed the firing pin assembly from another 1916 and installed it in the bolt. Inserted shell, pulled the trigger. It punched a nice hole in the filler/the primer as it should. Now the "mystery". Put the original assembly back in. Inserted another shell and pulled the trigger. It also punched a hole. What gives? Would a weak spring punch a hole in the soft filler and not even leave a mark on a "live" primer?
