Re: 6.5x284 shooters
With the most recent lots of Retumbo I'm getting velocities of 3000-3020 FPS out of two 6.5x284 rifles with 26" barrels and producing consistent .25-.5 MOA. Lapua brass, 140 Hunting Berger VLD's and Fed215's. Older lots were producing velocities of 2965 with the same charge of 59gr. Pressures appear to be the same, as are the ES which are running 10 FPS or less. Interestingly, both my rifles perform best with bullets seated .075" off the lands. I run my hunting loads at 2965 even with the newer lots of Retumbo because I use calibrated turrets. This requires backing off 1.5 gr. with the new lots of Retumbo. I am exclusively a deer and antelope hunter and found that the 140's at 2950+ are deadly from 50-1000 yards. No bullet blow up, and complete penetration, 1" entrance, 2-3" exit wounds on broadside shots.
