I have a 1-8 sfp scope with 1 mil subtensions.  1 through 5 mils.

I'm taking 8 ÷ 6 = 1.33.  So my 1 mil drops on 6x would equal.

1 mil = 1.33
2 mil = 2.66
3 mil = 3.99
4 mil = 5.32
5 mil = 6.65

Does this sound correct.

Thank you.

Your math is correct, but I have bad news. The 6 mark on your magnification ring is likely not exactly 6x.

Thanks for confirming.

I am aware.  I'll vet it all out actually shooting it but i wanted to have a ballpark starting point.

Thanks again.

That's a good ballpark, but best would be to get a "grid" target/paper, post that and measure gridlines with your scope at the various distances.

I don't do math but the reticles are usually set on the max magnification not the bottom. So I'd think the numbers are right for 6x. Unless I'm misunderstanding you.
