My opinion the the matter.
It's all a matter of self discipline really. Don't force a shot that isn't there. Don't take shots outside your realistic range no matter how great you bury em in thier on the range. Putting the arrow thru the vitals is the name of the game. Most deer shot very well with a bow go less than 60 yds. Never take a shot that you HOPE to make. Only take shots you KNOW you can't miss.
