I have a custom built 7mm STW from Robert Gradous. I need a good tactical scope for it. I will hunt with this and shoot from ranges of 50 yards out to 1 mile. I want a scope that has the best glass for my budget and i like the Zero Stop option. i think it will be helpful when i hunt or is it really that great of an accessory? My budget is $2000. I am looking for what scope yall think is the best for my needs.
