How much???

[avidflyer]

Cant get from 50yds to 100 yds on my annie 54. Most signs point to the way the barrel is clocked. Getting very nice groups for wolf target but when I tried to go up 7.5 mins. I only had 2 1/4 mins left in a nightforce br scope. Gonna shim the rear ring anyone have a guess how much I'll need to add 10 moa? Know theres a formula for it just dont know it.

It depends on the distance between the center of the front and rear rings. Measure that and post it here. Then we can calculate it and let you know.

20 MOA = 0.0055" per inch of ring spacing CTC

Assuming your rings are roughly 4 inches apart CTC and you want 10 MOA of extra adjustment...(formulate actual distance accordingly)

0.00275 x 4 = shim thickness of 0.011"
