Zero change in relation to elevation.

The zero was my question also. I was using Berger's online program to produce drop charts and just switched to Strelok on my phone. I think what was trying to be explained is that when you put the sight in elevation in the data generated for 8000ft would have that difference calculated in. Just the zero itself would be off. I will mess around with my app when I get home from work to see.

No have not verified the data for my hunting rifle (30-338 Win) yet. It was 1 click off for my 308 at 500 with the same program. My hunt wont be till next October so I will most definatly verify it before then.
