My build consists of:
Ruger lower with Rock river parts
Anderson upper
BCG and bolt from Brownell
BCA 20" 5R fluted barrel
I got to shoot it a few times yesterday. It showed real promise with 100 gr nosler ballistic tip with a 1 to 1 1/4 group at 100 starting with 28 grains 8208 at 2610 fps.
Factory Hornady 123 ELDM didn't fair very well with a 3 inch group at 2480 fps.
I believe they could have been into the rifling as when I tried to shoot my Sierra 120 gr loads the first one stuck in the riflings. I got a measurement and reseated them deeper.
I will get to shoot it again tomorrow and give another report.
