Hadijak, from the sounds of it you're not a country kid. There are laws against discharging airguns in pretty much every city or metropolitan area (and I'm pretty sure even moreso for killing varmits). If you're hunting varmits then you'd either have what you need, or know what you need.
tl;dr take your shit to airgunforum, or canadianairguns.
BTW turtleralph, do you actually need something 500+ FPS? I was under the impression you could ethically eradicate gophers, groundsquirrels, and such with a 495 FPS .22 (because of the extra energy afforded to a .22 going at 495FPS compared to a .177/4.5mm).
