If you can afford a nice 17HMR, then you can afford an Axis .223 or .22-250 or .243, etc. Walmart usually has them for $267 (give or take). A decent Bushnell scope, $1.50 in parts for the trigger mod, and you're under $400.
17HMR is ok for jack rabbit size animal but that's really about what it can kill reliably, in my opinion.
