hi guys, wondering if anyone has had this problem, i have a rem 700 5r long action and recently upgraded the bolt with a ptg one piece bolt with the m16 extractor. the problem im having is the extractor functions fine as when the bolts out of the gun and im pressing a casing into the bolt face, but when i insert a casing into the chamber the extractor wont catch over the rim of the case and acts like there isnt enough clearance for the extractor to move over the rim of the shell, has any one experienced this problem and what can i do to fix it? i thought about removing the material from the top the extractor with a fine file but i dont wanna ruin the strength of the extractor.
