The 17 hmr is pretty anemic in a rifle. Many 22 wmr revolvers have a 22 LR cylinder. Federal makes 50 gr wmr rounds that would be suitable for a pistol. Then you have the dinosaur 22 wr. It's loaded with a 45 grain bullet that has a velocity of 1,300 fps. The 22 wr is one of the best rabbit rounds I have ever used. The 22 wr has plenty of knockdown with it's flat nose and it doesn't destroy much meat. Trappers like the 22 wr because it has the power to take out larger animals without damaging the pelt.
All in all a 22 wmr is a lot more versatile than the 17 hmr.
