Dan, i got my barrel the same week you got yours. i was loading 26.0 gr. of varget down to 24.0 gr. and it shot fantastic, then i read your thread about you getting your barrel and loading 23 gr. of varget ,seemed kinda low but i tried it anyway. i shot 40 rounds in 20 minutes at 600 yards in a 4" group with exactly 17 moa. barrel was just warm.it was about 70 degrees and sunny. i also tried 90 gr. bergers with 24.0 gr. varget, same drop as the 75 gr. great barrel!
