What is the best way to make sure that your rifle is level when mounting a scope? It always bugs me because I can look and fuss etc...and then have other guys look and everybody will concure that the scope is mounted straight, but then later on I will be shooting at the range etc... and it does'nt look straight to me. I have done lots of rifles over the years, and except for buying some type of "system" for 30-50 dollars, have tried everything I know. I want to be confident that my scopes really are mounted straight. What works for you?
