Thanks guys, I had been looking at these enough to know what I wanted, and what was a good starting point. That said, I do not envision getting another rifle, yes a .22 caliber barrel and an extra air canister for the rifle, but I think I am good to go here.
A word on my compressor, it was nearly filled when I got it. I did add one cup or so or tap water, as well as the two bottles of antifreeze and purple ice. Spend about two hours today bench resting with my target at 40 yards. Plus we set up a play date for my daughter, my daughters friend's father and I shooting at 40 yards zeroing in the scope while our wives and the kids were inside making the salad and side dishes. We shot two fills so about 80 of the 50 grain .30 caliber pellets. He said this was the most fun he had ever had on a play date.
I still have a lot to learn about shooting from a scope and need to consult the manual big time. For instance, if I magnify too much, the target gets blurry. At 40 yards, a magnification of ten (or less) gave a clear sight picture from my Hawke Sidewinder. But as I increase from 10, the target starts to get blurry. Not sure if there is a focus adjustment so that I can dial the magnification to twenty and shoot at 40 yards. Will read the scope manual later tonight. The illuminated reticle is very cool, it's a very good scope on a great rifle. I was getting quarter sized groups at 40 yards - this with zero wind. But with a compressor and my set up, practice in the back yard is a snap, the hardest part is finding time when my two young girls and wife are occupied.
