How to tell if your scope is not holding zero?
I have two scopes in question. One is an old weaver that has seen at least 5000 rds on a lightweight 30-06. The other is a busnell elite 3500 that I used on my 338 Lapua for a short period. I put it back on my AR and I can't seem to get groups less than 1". So how do you know if a scope is messed up?
