RE: 22WMR or the 17HMR
If you plan on shooting coyotes, get the .22 WMR. It shoots a bigger bullet with a little more energy. Your range with either one will be limited. You want the bullet to deliver enough power to get the job done. The .17 HMR shoots a little flatter and chronographs a little nicer, but performance on paper doesn't always equal performance in the field.
