When was the last time you cleaned the inside of your bolt body and FP assembly?
I know a dirty bolt will cause a fail-to-fire when a bull walks by at 40 yds...........one of the more important firearm maintenance lessons I learned 45 years ago..........

Been a while since I cleaned bolt and pin, since it works fine with my handloads.
Mine worked fine with Remington factory ammo, but didn't work with Federal factory ammo.........
Seriously, pull the FP assembly and check/clean it.
