Here is what I iterated to with some more testing.
Berger 144 at 2750 with 36.6 grains varget with 30 thousandths jump. Overlapping hits at 800 yards. SD of five on ten round groups. Groups were 3/4 inch at 100 yards. 27 inch barrel and 3x fired lapua brass.
Barnes 145 at 2706 with 39.0 h4350 and same jump. Sd of 6 for ten rounds. A bit more dispersion with a 1 Moa hole at 100 yards than Bergers but ridiculously good for such a cheap bullet.
I did not miss all day with either load. Wind was a 4mph full. I could take either to a match with complete confidence.
