I shot my first deer, a doe, 15 minutes into legal shooting time of the first time I ever bow hunted deer. It wasn't until 5 years and several doe later that I finally connnected with my first buck which scored 126PY. My goal had been I wanted my first buck to be PY and I made it by one inch. The very next year I shot a buck that scored 172 and have shot 4 more in between those two. As far as how long it "could" have taken me or "could" take you is dependent on how selective you want to be. Those 1.5 year old bucks are dumb as heck and easy to get close to...a mature doe is harder to kill than one of those young fellas. Best of luck to you!
