i have shot 2 fox and a coyote wiht my 17hmr, the 17 grain v-max suck for fox and yotes, you have to use the hornady 20 gr xtp hollow points, head and neck shots are good, but if you could hit the front shoulder you should be good, i rolled a fox with the 17 grain v-max and never found it, so if your gunna use the 17hmr use the 20grain xtp's and make good shot placement, and its not loud so u wont wake your neighbors
