Try removing the bolt assembly and soaking in some Coleman fuel and let it sit for a few minutes, then slosh it around in the gas, then air dry and try again. I had a similar problem with a Weatherby Mark V lightweight .30-06 some years ago. Turned out to be crappy headspace on crappy Hornady factory ammo. A bunch of rounds later from various factory loads and my hand loads and nary a misfire. After cleaning bolts like that, I put a super light coat of Ballistol on the exterior of the bolt and then wipe off. Happy Trails
