I put the eccentric inserts into the Burris rings to walk the scope into the bullseye. I'm closing in on it. The OnTarget software says that this is a 1.005" group, centered 0.538" to the right and 2.220" low. That's a big improvement over 5.5" right and 2.9" low. Ammo as before was the same lot of Remington Premier Accutip 55-gr, MV=3240, BC=0.242.
