First, I've never done it before so I'm sure my aim will be bad. Second, the deer will run when he hears the gun fire.
I'm guessing it'll take 30 to 40 shots unless I can somehow corner the animal.
After months of doing this and practice, I can probably get it down to under 10 bullets.
Or you could sit in a tree with a billy club and when the deer gets under you, jump on its back and beat it to death with the club. lol
But seriously, an individual should be allowed to choose for himself (or herself) what works best for them.
