I am in need of a new varmint rifle and was going to get a .223 but after looking I think thats a little more than I need. I plan on shooting 150-200 yards max just around home for woodchucks and maybe a coyote if I can.So my question is between the 22 mag or the 17 hmr. Anybody have experience w the 17? I heard it was faster but has a smaller bullet. Thanks.
