The rifle heaspaces off of the shoulder, not the projectile. Pulling the projectile will only push the round back into the bolt if you are forcing the projectile into the lands.. which will cause a pressure spike.

That said, the extractor is most likely going to hold the round back well enough for a proper strike.


I'd check FP protrusion and set it near max recommended (there is a how to on the front page). I'd clean the bolt and the FP channel (full disassembly), and I'd get your headspace checked to see if its off.
