[QUOTE="Wild_Bill, post: 2225695, member: 4785"] The issue with running primers in 6BRs is the projectile weight. If you are running 100gr plus projectiles use either the CCI450 or Rem 7 1/2, they are slightly hotter and work better with the slower powders at a larger volume. The other one is the CCI BR4 all of the 3 mentioned have thicker cups to hold the higher ignition pressure from starting to move heavy projectiles, the same is true with ant 308 or CM case with a small rifle primer. If you are running sub 90gr projectiles anything except the Rem 6 1/2 is GTG. [/QUOTE]
