Have put well over 1400rounds through Shaw barrel now and had a chance to shoot on calm evening just before dark. Shot at 100yds 70deg I was sheltered from wind. Also shot 2 other ARs and RPRF was my practice while letting others cool down.
Ammo used was SK Rifle Match and barrel was scrubbed clean about 50 rounds prior to this Target. (The 50 round fouling Target also pictured below but was shot over weekend under different conditions).
22LR groups are bottom two rows; First two cold bore shots when wayyy low but I have sort of come to expect that as wax/lube in barrel is cold and grippy.

Bottom line: depending on how you measure, my 22lr is more precise than my 2 precision ARs! And it's getting better. At least for my rifle, precision is not an issue.
