I'd throw this on /k/ but it's more guns and military, whereas hunting is an outdoor activity.

I want to start deer hunting. I'm 19, almost 20 and have never been hunting because of my dad's poor health when I was a child. He's better now, and I might start hunting with him.

I've got 8mm Mauser, 303 British, and 7.62x54 to work with.

What would be the best out of those three to hunt deer with?
