personally seen deer shot with 22 hornet last year didnt like the idea of it and tryed to talk the young girl into practicing with my grlfriends 243 but no way was not happening not wanting to deny her her youth day hunt we went with the hornet took a deer a littl bit back just grazed lungs did not exit from 45 yards. no blood trail whatsoever deer went 100 yards tops. and layed down we didnt wait long enough and jumped her. went home had breakfast, called in some help, waited a couple hours and founf it within another 50 yards of jumping.
my advice would be with any of the small calibers would be to give them extra time and get help to track bloodtrail may not exist
