often times, the deer is severely wounded and manages to get away, only to die or suffer till it's wounds heal; or to be killed by coyotes and eaten. however, a close well placed shot is often sufficient to kill the deer quickly. hope this helps...:-)
While it may, most states forbid their use for hunting large game animals, simply because you'd need several shots to do so. All concerned hunters prefer a clean kill to wounding an animal and allowing it to suffer.
Not advisable, you would more than likely just wound it and possibly cause it a long slow death! Use a 30-30, a great gun for hunting deer or a 270,30-06,7mm 243 is a fast gun but with a smaller round, which is fine if your a great shot, a lot of wounded deer out there from poor marksmanship
It will if shot in the right place, however it is illegal to hunt deer with a .22 caliber. By law I think it has to be a .30 caliber or bigger....I personally use a 30.06 or my .44 magnum super red hawk.
