R_H_Clark: I think you misspoke when you stated your groups "could be up to 1/4" off at 50 yards" - with the 1/2" adjustable click scope at 100 yards scope?
IF... your groups were 1/4" to far left at 50 yards then you should simply move the adjustment 1 click to the right and that would put your groups dead center (1/4" more back to the right!)!
I think the most/maximum your groups could be off at 50 yards is 1/8" (.125") with the 1/2" click adjustment scope?
Am I not correct?
In other words if your groups center was 1/4" to far left at 50 yards simply adjusting it one click right would make your groups center dead on with the 1/2" adjustments at 100 yards scope.
I have a case of the dyslexia so I could be wrong - but I have been adjusting scopes for 52+ years now using the above method/contention.
Please correct me if I am wrong.
