I have an 1892 rifle, made in 1913, that has been re-barrelled with a 357 Mag barrel. Very nice condition and cared for.
I’m getting about a 10% misfire rate with half of those rounds firing on the second try. Both 357 and 38sp rounds.
The action cycles fine.
Is this just an obvious firing pin problem, or could it have something else going on ?
What would the repair be if anything besides replacing the firing pin ?

Bill,
How is the head space? With a replaced barrel that would be one thing that would of changed. The other thing to look at is a weak main spring.

Bob,
Although I can research and watch videos about the receiver disassembly, and probably replace a firing pin and main spring,
I am at a loss how to measure, evaluate or modify the headspace. Can you point me to something that may address that ?
Last resort is a gunsmith, which I prefer not to do, but will if necessary for function and safety.
Thanks for the help.

Bill,
Does the bolt push the cartridge up against the barrel firmly? If there is any slop between them when a cartridge in there then the firing pin has to travel farther which can cause a misfire.

Bob,
Everything locks up tight, and cartridge seats flush.

Bill,
Then you could have a main spring weak, Someone dressed off the end of the firing pin making it shorter, or the firing pin is being restricted in the bolt. You could compare the main spring if you had another gun to compare the spring pressure or swap them.
