Re: Are cci br2 primers a bad choice with Retumbo?
I shot the 115 berger in my Tikka 22" and tried like heck to make the Retumbo work, since I had a bunch. Ultimately it was IMR 4831 that worked best. 52 grains behind Fed210. After a couple of bad experiences with the berger on 3 deer, I tried 100 gr tsx and 110 accubonds. Again, after trying r15, r17, r19, r22, imr4350, and Retumbo, I found that 4831 was the best for both. All loads are sub-moa past 200 yards, with some groups down into the .3-.5 range. Velocity on 51.0 grains pushing the 110 accubond ~3020, which is a little slow.
