ive had a 17 hmr for 2 yrs and absolutly love it. the 17 hmrhas a distinct advantage over the 22 wmr in velocity, trajectory, and accuracy. if your shooting larger game with the 17 you might want to get the 20grn. XTPs. they act more like a big game bullet than a varmit bullet. if your shooting beyond 100 yrds i would definatly go with the 17 hmr.
