Case in point.
Target on left was two weeks ago, target on right was less than 20 minutes ago. Has rode in a truck during that time. Same gun, same lot of issued 77gr Match, no adjustments to scope.
Prone mag monopodded, unsupported. Two MOA shift right. Rings still tight.
This scope is the best 1-6x on the market in my opinion. Unfortunately it's also another Vortex going back.
