Marlin 336RC Firing Pin Protrusion
Well the front firing pin tip decided to go south (popped off) this weekend on my first year (1948) marlin 336RC (my hunting buddy decided to dry fire it a couple of times too many).

So I disassembled the bolt and ordered a new front FP from brownells this morning. Question is how much protrusion should there be on the tip. I remember Jack indicating 0.055 - 0.65 for my swedish mauser but am unsure for the old 336RC in 30-30.

standard firing pin protrusion for a center fire rifle is .055" plus or minus .005"

You will find a few rifles that fall in the low side of these dims, but not many.

If you go over .065" then you run the risk of punching a hole in a soft primer.
