As long as you have trued ballistic data on whatever caliber you are shooting and know the value of the bdc sub tensions you can use virtually any caliber and any bdc. For example, my scar 17 with vortex gen 2 1-6 sub tensions are as follows according to vortex:1st subtension-2.4 moa
2nd-5.6 moa
3rd- 9.5 moa
4th- 14.6 moa
Having the ballistic data from the load I shoot I know that 2.4 moa=253 yards
5.6 moa = 372 yards
Etc.. Also depending on your selected zero yardage. Mine happened to be at 100 yards.
