Out to about 200yds a .17HMR is a whistle pig's nightmare. They're fun, cheap to feed, and they're a small caliber laser. Beyond about 250 it starts getting real touchy and you'll want something a little bigger. Personally, I really like the effect of a Remington 700 in 6mm Rem. or 7mm Mag for the ones waaaay out there.
There's an old chinese proverb about not using a cannon to kill a mosquito--obviously they never tried it, because it's a whole lot of fun!
