I started at 60.8 grains of RL26 for 3,010 mv out of a 22" barrel.

I then lengthened the COAL bumped up the powder to get better accuracy and a little more speed.

I bumped the COAL to 3.40 from 3.35

3,080
3,074
3,103
3,061

Accuracy was just under an inch with the cold bore shot.
3 shots were touching.
The Partition likes the slower powder more than the LRAB.
