It will work , ive shot deer on damage permits with the same stipulations. 22 wmr or .17 works at close range, I usually went with head shots but if you break the neck same results. Just seemed to me the head shot was a bit better target . like others said if you miss the neck bone you likely won't find the deer. like most small caliber guns blood trail will be pretty much non existent. Wait for a good close shot and he'll do fine.
