I've shot the Baracuda Greens in my .22 R9, it loves them and shoots them very accurately. They seem a bit overpriced, at least at PA. The FTT Greens might be a little light for a springer. JSB has come out with a Lead-free pellet, Straight Shooters has them.
Of course you'll have to see if your gun likes them, only one way to do that. Something to keep in mind is that some lead-free pellets will not group if there's any lead in the bore, so clean your barrel before you test for accuracy. Pm me and I'll send you a few to try.
