The CZ 452 .17HMR I own is one of my favorite rifles. Trigger is awesome, and the gun is very accurate. When I first bought the gun, I used a Burris Fullfield II 3-9x40 on it (which worked pretty well). However, I recently replaced it with a Sightron SII 6x42AO HBR scope. I was worried about the magnification at first, but I have found that 6x is plenty enough for 150-175 yards. Out to this distance, crows and other varmints don't have a chance.
I highly recommend Sightron scopes, and have been very impressed with them. Mine has 1/8" clicks, which are perfect for the .17 round. Plus, it came with target knobs and a 4" sunshade. Glass is as good (if not better) than VX-2's and Fullfield's, and not far behind some of the far pricier brands. I also have a 4-16x42AO SII on one of my .223's, and I don't think you can beat these scopes for the money. Not only that, their warranties are second to none. I recently had a very minor issue with one, which was more cosmetic than anything. I shipped it to them on a Tuesday, and had a brand new scope the following Wednesday!
Here's a pic of mine. The picture didn't come out as well as I'd liked, but you get the general idea...
How does a Leupold riflemen compare to a Burris Fullfield 2 or a Bushnell Elite 3200?
With the exception of the price, the Rifleman doesn't even begin to compare to the other scopes you've mentioned. First of all, the Rifleman series doesn't come with click adjustments. It has friction adjustments, so repeatability is an issue. That in itself should exclude it from your search. Then, considering the glass isn't on par with either the 3200 or the FII, then you'll quickly see that its not even in the same league. The only thing the Rifleman has going for it is its relatively small size and light weight. Problem is, Leupold has scrimped so much on every thing else that its not worth it to even consider (especially for close to $200). For $175, here's what you get with the Rifleman: 3-pc tube, non multi coated lenses, and friction adjustments.
For under $200, I cannot recommend the Fullfield II enough. Finger adjustable turrets, excellent glass, and the Ballistic Plex reticle works well with the .17 HMR round.
