the 17 hornady will be nothing like the 17 rem.you can't compare the two,ones a centerfire the other a rimfire,no compareison.the 22 mag in my opinon isn't enough for coyote,there for the 17 hornady will be less effective.this isn't to say that the 22 mag or the 17 hornady won't or can't kill a coyote couse they will but if one wants to get serious about huntin coyotes a larger round should be used.
