I installed a DAI Mgt. Scope mount on buddy's No4 Mk1. He had a Ruko (?) 2.5x he wanted installed. Weaver rings. All went good but when I pulled the bolt to bore site it on the x I have on my back fence 25yds away, I ran out of "UP" adjustment on the scope. It's about 4" low, which should be kinda close @100 yds but I suspect I'll need to shim. Just a ball park, anyone have an idea of shim size required in the front mount to give him some up/down adjustment? Thanks!

I would use the same calculation that we use for adjusting front blade height.
Multiply the distance between the front and rear scope mounts by the error in elevation at the target. Then divide the result by the distance to the target. Example: Distance between mountings 4". Elevation error at target 6". Distance to target 900" (25 yards x 36) (4x6)=24 24/900 = 0.026" Raise the front mount by 0.026" (26 thou) Make your own measurements and see how you get on. |

It's nice to be important, but it's more important to be nice!

Thanks Zed. Will plug my numbers into that formula.
