Howdy, Greg, and welcome to our little nut house! I skipped a couple of steps in the addictions process, I started with a CFX a little over 6 months ago. Since then, I've added a Diana 350 Magnum .22, an IZH 61, and a Crosman 1377. The CFX has just recently been converted to a gas ram, so I'm still playing with that. Good shooting with that Shadow. I don't own one (YET!), but my boss does, and I've used it a lot. Totally changed my mind about fixed vs. break barrel in the accuracy department. I'd really like to do a gas ram conversion on a Shadow, just to see if there's an appreciable diffefence in the two.
Regarding that Leapers 8-32x56, I'm pretty sure it would be too long for the CFX. Don't know if your'e familiar with the rotary loading breech, but it's can be a real PITA to load if there's a scope hanging over the port. By the time you factor in eye relief, around 15 inches is about all the scope length you're going to be able to use. So far, in big glass, I've had a Leapers 3-12x44 full size and a Simmons 44 Mag 6.5-20x44 on my CFX. Both worked fine, but just barely. If you have long arms and want to increase the LOP, you could add a spacer in front of the recoil pad. I did that to mine and it worked out well, although it isn't on there now. In the process of doing other stuff, I took it off and just never got around to replacing it. Anyway, speaking of long winded :-), hope this helps, and look forward to seeing more from you. You've found the best little air gun forum on the web to hang out in, so kick your shoes off, put your feet up, and relax!
