I recently purchased a Cooper Arms Mod 22 Varminter in 6mmBR, complete with test group you described, here's a pic,
As you can see there is no indication of what distance the group was shot at, although their website leads you to believe that it is shot at 100yds.
You say it is shot from a machine rest, they say from a bench with bags???
If what they say is untrue then they are slightly missleading their customers.
The rifle itself is an excellent performer, superb quality and i am very happy with it.
I am currently developing loads for it which so far have not exceeded 1/2 MOA.
PS. The group by the way measures .042" [img]/ubbthreads/images/graemlins/smile.gif[/img]
