Welcome aboard, Jason!
Don't know about the Shadow Sport personally, but I've shot the previous model, the Shadow 1000, a lot. Great gun. I've seen a continueing review of the Sport on another forum, it's doing quite well. If anything, it seems stronger than the old Shadow, and just as accurate. In short, I think it would be just the ticket for what you're looking for. One suggestion-- avoid the Gamo Raptor pellets. Some guys have gotten good results at shorter ranges, but they are so light, it seems possible that continued use could actually damage the higher powered guns. I've had good luck with mid weight pellets, RWS Superdomes and JSB Exacts, 8.3 & 8.4 grains. Lots of guys like Crosman Premiers, others like the heavier Beeman FTS and Kodiaks. Interestingly enough, Gamo guns just don't seem to do that well with Gamo pellets. I don't anything about the new scopes and mounts. The older ones had some okay scopes, but the mounts left something to be desired. Like, not moving. Anyway, hope this helps, and keep us posted on what you end up with. BTW, look around the forum, there's tons of info right here for the browseing.
