Well, since I am now completely confused as to what a mature buck really is I can't answer that question[8D]

The last 3 years I have averaged 23 sits per shot at a trophy buck, so probably around 69 hours. Wow, I didn't even plan that!

Over the last 5 years it would be around 109 hours since I blanked '03 & '04. I have no idea further back than that, but I wasn't very picky back then either.
