I've only ever killed one buck per year. Mine is pretty low @ 37%.

16 years hunting, and 6 bucks. I attribute that to the first 5 years hunting in Vermont only (5ish deer per square mile, still managed to kill some does). From age 16 to19 I was shooting anything that walked and was legal. From 20 to 27 y/o (this past season) I've taken 2 bucks, not for a lack of opportunity but because I tried to start getting selective. Every year in this time period I've passed at least 10 shot opportunities on legal deer that I just didn't want to shoot.
