There is tons of deer killed every year with a 22 mag and head shots.That is the way the control deer in city limets now days.They hire guys to use night scopes and 22 mags.They head shoot every deer they can. It was just done in KC Kansas.Guy went in to a park at knight with 22 mags and shoot many many deer.All in the head.
AS for oobuck.That is mean shoot.Out to around 50 yards it will drop deer every time.I dont do much hunting with a gun any more at all.I do knot many old timers that pack buck shot around with them when bird hunting. They fill there deer tags every year that way.I just hate to help them cleen there deer,after a shot like that.From what I have seen.You normaly get 4 to 8 pelets in a deer at 40 to 50 yards.Just seems like to many of them are in the guts to me.
I will stick to my arrows to do my killing.No head shots with the old bow :{
