I fully disassembled my bolt the other day. Polished the bolt face, ejector, and smoothed up the extractor a little to. I also polished the cocking ramp and the face between the main bolt body and handle part. While I was at it I clipped 2 coils from the firing pin spring. Sprayed it all down with hornady one shot cleaner and lube and wow it feels good. Shot it a few times and no more brass shavings on the bolt face and no more super heavy bolt lift. If it comes back it’s gotta be something with the chamber
How many rounds have you fired after clipping firing pin spring? Any misfires or other issues?
