Welcome Tom,
As far as I know, they aren't out yet and won't be until mid June. Then, like the Xl, it'll take a week or two to get into shooter's hands before we hear a number of reviews.
As far as in put, IMO, with the 25 cal XL listed at 750 fps, verses the 22 cal XL's 1100fps, plus higher cost per pellet shot, I don't see any advantage.
Paul.
