I just sent a e-mail to Spook. Basically, I get horrible groups, 4-8 in. I've tried everything from 168 gr hpbt molys to 240 gr smk's. Subsonic and supersonic. With and without the can. Dirty gun, and more recently after cleanning 10 time, with everything I have, Butch's, Isso, Shooters Choice, brushes and patches. I've taken it back to the gunsmith who built it, and he can't figure it out. I tried a new RRA mount today and still bad groups.
I can shoot 1/2 in groups at 300 yards with my .308, and one hole groups with my .223, so I don't think it's me.
