what scope would ya'll suggest for this rifle. i would love to put a Leupold on it but they are out of my price range. i will be shooting this rifle from 0-400 yards, so i am looking for an adjustable scope that will adjust up to 10-14 power and atleast a 40mm objective. i kinda like the Nikon Pro Staff 3-9x40/50 but i dunno if a 9 power scope will be suitable for my needs.
