Thread: How to do duel Zero. Sub/Super

The method I use is a simple Mil dot type retilcle, Then rather than do a drop chart and adjusting I simply work out the confirm what ranges the dots are for the two ammos.

EG with my 303

Load 1 Zero is at 100m and is the next dot down at about 175m (Big RN slow bullet like throwing a hammer)
load 2 is zero at 150m and the second dot down is at about 225m. (Lighter faster bullet)

If I look to what load I have in I know the distances that this load matches the marks on the cross hair. So I do not need to adjust anything regarding my scope. I just need to know what ammo is being used.
