Thread: reticle-bore alignment

I was testing my scope alignment by drawing a plumb line on the target . winding up 10 moa and checking the bullets landed in line with the drawn line. the end result was a 4 degree shift left with the 10 moa adjustment. I like to make measured adjustment rather than twist and 're-check etc so I looked at the value of 4 degrees from the center to outside edge of the scope tube. seems that the formula for a one inch scope is .2mm rotation per degree (it's not exactly .2 but it would be unrealistic to deal with numbers smaller than this). just if anybody was interested
