Does anyone use a scope with 1/8 adjustments? I was checking out the Nikon 5-20 and it has 1/8 adj. Will this work out to say 700 yards? I'm up in the air between this monarch, a leup 6-18, and a leup 6.5-20. I really like the new monarchs, I'm just afraid of that 1/8 adjustment. Any thoughts/opinions will be appreciated.
