Hi All,
For those who, like me, are or were having a problem with 'velocity challenged' 6XC loads I found some tweaks that helped. My OAL was very short,ogive barely out of the case). I realize one wants room to seat bullets out with eroding throat but there was room to adjust. Lengthened my throat 0.100' and picked up 2 1/2 grains worth of space,and velocity). I also ran a variety of 'jump' lengths from .080' to touching the lands. At .040' velocity was up a bit and accuracy was still sub-moa. I ended up with .020' off lands for solid 10-shot 3/8' groups at 100 yds. and 3-4' at 600 yards and called it good. I know everyone seats their bullets into the lands for long range but this seems to work. Will shoot another 1000 yd. match next weekend and see. Bottom line I went from 2850 fps to 2970 fps,not much but every little bit counts at the 1000 yd. line).
Good shooting!
