Thanks for the help.
I know that at least one fires good groups without the moderator and that several moderators have been tried on that rifle. This led me to believe that the thread was not cut correctly causing the mod to be mis-aligned and the bullet could be clipping the mod. However all three were purchased brand new and supposedly factory screw cut!
Just wondered if there was something going on at Anschutz!
When I get home I'll have them check the crowns!
Thanks for the tip regarding the pellet
I'll dfinitely pass that on when I get home
