Re: 30-378 Wby using 200 gr Accubonds or 210 Bergers.
Broz, I am breaking in a new barrel (factory dimension chamber) with 115 gr US 869, 215 M's, 200 gr Accubonds. About 1 moa (cleaning between shots). Also loaded some identical loads except with 215 primers. Only 6 rds fired, no speed reading. Got rained out. In the other barrel I got 1/4 moa with H-5010, 215M's, 190 Smkhp's. I set oal on both loads to get full neck engagement. I like the 869, but haven't proved it out yet. I'm looking for 1/2 moa.
Good shooting, Tom
