On my x-bolt [7wsm] I have a Nikon Buckmaster 3-9x40 BDC. Works very well. Most consistently accurate hunting rifle I own.
I just bought a Redfield Revolution 3-9x40 for a different rifle. Only fired a few shots with it, but so far I like that one too. The Redfield sure zeroed quickly. After mounting I bore sighted by squinting down the barrel with the bolt out. First shot was on the paper, but only barely. I cranked the adjustments over and a bit up. The next 3 shot group was a perfect 2.5 inches high and right in line. Group was 0.7". I was impressed with both the rifle and the scope. Like I said, the redfield hasn't seen much use yet, but so far I like it a lot. The Buckmaster HAS seen a lot of use, and it's rock solid. I have another buckmaster, and it's been covered in thick wet snow, and been used in all sorts of bad conditions, but still works great. I also have a Bushnell 3200, a Simmons Aetec, a Vari-x II, and a couple VX-II's. The only one I'd recommend against is the Aetec. It's super clear, but one time the reticle broke. It got repaired by bushnell without too much hassle, but now I think I detect a slight quiver in the reticle again. I might be imagining it, but...
The Bushnell 3200 won't steer you wrong, but it seems like the magnification is a bit lower than the other scopes when all are set a 9 power. But it's still clear and works fine. Actually, I've shot more deer the past 3 years with that scope than any other, just because that's the rifle I've had in my hand when the deer pop up. Of course the leupold's are good, but cost more. If I were buying a scope in the $200 range, I'd buy the Redfield but only because it weighs 4oz less than the Nikon. If weight weren't a concern, then I'd get the Buckmaster.
