I'm posting here in competitive shooting in hopes someone will have an idea as I'm stumped. Problem is snug chambering closing bolt.
Reloading 264 Win Mag with Redding FL bump die and bushing dies. Cases are all trimmed to 0.005 -0.007" under specified case length. When sizing, up to +0.008" shellholder, it has no change in bolt closing pressure.
Marking case with Sharpie on belt area shows no interference. Case neck angle may show some contact but no change in pattern or pressure despite 0.000 to 0.008" shellholder.
Have never had a situation where bolt was really tight, but I'd like to remedy the pressure to protect the bolt lugs and believe it could be affecting accuracy. Gun is Sendero and shoots under 1 MOA.
Any ideas?
