RE: what size scope?
I own Bushnell, Leupold, Simmons and Nikon scopes. The Bushnell Banners are on my ML and shotguns and I can't think of a better bang-for-the-buck scope out there. I use the 3x9x40. With the ranges and accuracy that the newer ML's are achieving, I wouldn't pass on a 150 yard shot. I have gotten them at my local BPS for about $80-90 on sale.
