I recently worked up a load with RL 26 and 160 gr Accubonds. Most accurate was at 61.5 grains. Velocity at 3010. Seated to 3.340 COL. Using quickload, which has had the burn rate adjusted to my current lot of RL 26, it shows that with the 140 gr Accubonds, you should top out at 65.5 grains and velocity at 3247. Of course you should work up to that and verify.
