i see no reason at all too have more than a 3-9 power scope on a deer or big game rifle. Most times a fixed 4x scope is more than enough.
One of my all time favorite scopes is the Bushnell Elite 2-7x32. It's a fine piece of machinery. After using the Elite series with the Rainguard, I always look there first. It rode on a Remington 7400 in 30-06 for over 10 years and about 1500 rounds, and NEVER needed to be re-zeroed. In trucks, on quads, being dropped, hot, cold, wet, dry, it never failed me. I've had similar success with the 3-9 and 4-12 power models.
My 2nd choice in optics is usually a toss-up between Nikon and Burris. I really like the various Nikon lines, but they are a bit bulky in some models. Burris scopes are usually a bit more compact, but cost more.
Leupold sucks. Sorry to say it, but I've had more issues with Leupold scopes than I have any other brand, even the cheap stuff. I've had Vari-X I and II, Compact, VX1, VX2, and Rifleman. Leupold is the ONLY scope that I've ever had totally de-gas as well as having the cross hairs break on two different scopes. The optic clarity/resolutin in the Compact 3-9x32 was so terrible that I had to use my binoculars to make sure that a deer I was watching at 100 yds was actually a spike. I couldn't tell through the scope, at any power. Same problem with the Rifleman 2-7. The ONLY thing that Leupold has going for them is the fact that they are American made. They are totally overpriced for what you're getting, which really isn't much, IMO.
