the 2nd one,was a perfect broadside shot at 23 yds..
It was not perfect - if it was the deer was down in less then 100 yds and anyone willing to track would find it.
So yeah,it can happen,but your chances are pretty slim if you put the bullet where it needs to go
Same with an arrow - put it where it needs to go and the deer dies quickly..
..I practed for almost a full year before taking my first deer hunt..I am an excellent shot,and i started shooting in 3D tournaments,and I think im doing pretty well,so no its not my shooting!
Being a good shot is only part of it.
Knowing when to shoot and where to shoot are as important.
You don't seem to be willing to learn that, so it is best you give up the bow, stay with the gun and stop trying to hurt other responsible hunters.
