Background:
I'm replacing my riflescope on my Savage 243 Win with a Vortex Diamondback 4-12x40. Said scope has 70 MOA of elevation adjustment. I'm using a DNZ Game Reaper one-piece mount and rings.
Data:
There is a 1000 yard match coming up that I want to try out. My ballistics app says I need to come up 34 MOA from my 200-yard zero. That is almost half the total adjustment capacity in the scope. My previous scope used up almost all of its adjustment capacity, 39 out of 50 MOA, just to zero at 200 yards.
Possible Solution:
I'm thinking about adding a shim under the rear of the scope mount to give me some more elevation without using up the available adjustment on the scope. Yes, I know DNZ sells a "+20 MOA" mount that might accomplish what I want, and that's what I'm trying to emulate here. Honestly, I don't know if adding 20 MOA is enough to get me where I need to be. If the new scope uses the same almost 80% of its adjustment capacity just to zero at 200, I'll need 55 of my 70 MOA to zero, leaving me at least 19 MOA short.
Questions for the group:
1: How thick of a shim do I need for at least about 25 MOA?
2: What should that shim be made from for a blued barrel?
3: In what way and to what extent will this impact the validity of a ballistics calculator app?
