Start running into some compression with above combo, but SD?s in 4 barrels have been under 10-comfortably. Have shot a lot of CFE, a bit less 8208 and ARC just seems to fall in place with a lot less effort. Will continue to work with others, but am laying in ARC for the long haul.
You can vibra settle it. Ar-comp settles perrty good with a sonic toothbrush.
I'm running the 120 gold dot in my 16 and 12.5 ar grendels at 2.290 and 28.6 grains. No pressure signs, very well behaved during the ladder work up and the ad and ES is stupid low.
