RE: a bushnell banner 6-18-50mm new is that good scope
I would not go with a 6-18 unless you are shooting 300+ shots.
If you hunt in conditions where the avg. shot is 100yds a little more, a little less. I would go with a 3-9 or something like that. Most deer hunters have no need for a 6-18 scope. Remebmer that a 3-9 wiill also gather more light.
