Over 3000 fps was best results. 3021 fps had the greatest velocity.
.01 off the lands was best all around.
Best powder was between IMR-7828 AND RL-22.Powders used was IMR-7828,RL-22,H-1000,H-4831.I used these powders because they cover the ranges for so many others as far as sensitivity and burn rate.
surprising to me and the other 4 shooters was how poor h-1000 was in comparison. :dunno:
Grouping (average)Was just under .75 M.O.A at 300 yards between the 5 shooters with 5 rifles on a lead sled.
Rifles were warmed up as well as the shooters,Each shooter shot a total of 64 rounds.10 from each powder with 5 rounds .05 off lands and 5 .010 off the lands.3 each from each powder and half of them were .05 off lands and the other half .010 off the lands.
Only 5 shots were fired at a time for velocity rotated to next shooter and only 3 shots were fired at a time for grouping before rotating to next shooter.
I HOPE THIS TEST THE WAY IT WAS DONE WILL HELP OTHERS. :tup:

and
79.0 gr of H1000 @ 3020
Both with 200 gr Partitions
Although the H1000 was shot through a pro chony and the RL 26 was shot through a magneteo speed
