After working with a couple of other firearms on Monday morning, I moved to a 50 yard bench. I rested my CZ 452 UltraLux on the Caldwell RockBR rest and fired a five shot group to assure that cartridges from a new brick of Wolf Match Target would shoot to the same POA as the former lot.
I was satisfied with the zero, but next time, I am going to try this with fresh eyes and try to put 'em all in the ten-ring.
