Home Forums Hunting & Shooting Ask The Gunwriters 6.5 Weatherby RPM Mo betta than a 6.5PRC??

I picked up a box of Weatherby 6.5 RPM 140gr AB ammo, and yes its just an extended 6.5-284, I pulled the bullet and got 64.6grs of powder, looks like/similar R23 but not positive.

I got 80.1grs of H2o, the loaded length was 3.333", here's a cpl pictures for comparison,
