RE: Exit hole's.
Well with my shotgun, i allways get holes that are big. Lost deer I shot hit her in the hind legs while she was running, thought she was about 40 yards, turned out to be about 80. Even tho my shot was a luck shot and I wasn't aiming at the legs either. But boy o boy did she go down in a hurry. Walked up to wear she dropped and she was gon. Found the blood trail that Ray Charles could follow. She was still crawling with her front legs. But I like big holes, as long as you do get a good heart/lung shot you arnt ruining much meat. And plus I doubt you are really gona notice the amount you lose from the enter/exit holes.
