The 460 is one of my favorites (I have a few favorites, Lol). I'd lean towards getting one in .22cal as the .177's can shoot a little hot out of the box. Mine in .177cal shoots ~10.5gr pellets around 920 to 930-ish fps, domes seem to fly alright at these speeds (mostly)... 10.5gr H&N Barracuda Hunter hollow points will spiral (destabilize) out past 40y with any hint of a headwind. No problems pushing .177 JSB 13.4's to respectable velocities either, although you give up a few FPE at the muzzle, you'll retain more out past 50 yards. My 470TH (same action different dress) in .22 shoots right around 24ftlbs. and not too pellet picky. Both are potentially very accurate, limiting factor usually related to shooter skill with springers. That being said, the 460 (and related) are relatively forgiving as far as "magnum" springers go. The only negative to the 460 (in my opinion) is the width of the front sight. If you like the 460 but prefer open sights try and find a used Diana (Mauser) K98 springer, again same action different dress (unfortunately out of production).
Figured I'd add mention of the Diana 350... Same power as the 460 but a bit lighter. You'll give up a bit of stability but much nicer to carry in the field. In all reality most folks don't need the extra gusto of a magnum springer. The nice thing is Diana's are very simple to work on, if you decide you don't need full power a simple spring swap is all that's needed.
