need some 50-60 grain bullet and powder charge recommendations. Ar10. 38 gr varget only one tried so far. Grouped in or under. Didn't measure mv. Thank you.
 
I shot 60gr Sierra TMK with 38.6 gr of H4895 @ 3747ft/sec with an SD of 2 (3 shot group), 1 tiny hole @ 100 yards. Hornady brass, 210M Fed primer.

Start lower than this and work your way up, also be aware of the brass you are using, I have tried 3 different brands and ended up back @ Hornady.

What twist barrel are you running?
 
1:8, 22" X-caliber.
Just shot it again this morning, the same load, 2 groups were cloverleaves, then I added the suppressor and it appears to have fallen apart 1.2" group, that is the 1st time the supressor had this affect, usually groups get better in my experience. Oh well this means I get to shoot more.
 
Shot some more 60 gr TMK today with Varget 39.5, 40.0, & 40.5 gr, lows were 3700 highs were 3800 ft/sec.

very similiar results with IMR 4166, tried 39.5 & 40.0 gr, 40.0 was just under 3800ft/sec.
