I have a relatively new Rem 700 Stainless LV, .223 Rem. One problem I can't seem to correct is that it craters primers, with all loads. It's not a pressure problem, since I'm using relatively mild loads.
Other than the crater at the firing pin hole, the rest of the primer is not flattened, but perfectly normal.
Accuracy: Grouping is only about 1.25" at 100 yards, but same loads in another rifle does 1/2".
What I've done:
Taken the bolt apart and cleaned/lubed the firing pin.
Checked pin protrusion... .050" It's the same as other 700s.
Replaced the firing pin spring.
Replaced the bolt shroud with a non-locking one.
Re-checked the sizing die setting and have minimal case fit to chamber.
Varied bullet seating depth from zero to 1/10" to lands with no results.
Any suggestions?
