RE: 22 mag deer
When we butcher our beef and hogs thats what we use,one shot to the head,BAM flop.It will work on deer also,seen it with my own eyes.Shoot them in the head about 2 inches down from the top,or as they feed by they put their head down and behind the ear right at the base of the neck(I'm talking 40 yds or less).
Now is it the right gun for the job,heck no.A person would be better off with a 243 or larger for deer.
