Congratulations on the buck - very nice. And a very nice bow too. Looks just like mine.
My Z-7 is going on 5 years old now and I still think it is the best bow ever. I bought a newer model a couple of years ago (Z-7 Extreme) but usually always take my old Z-7, especially when hunting out of a tree.
Did you kill him hitting a feeder or somewhere else? I have shot one deer this year out of one of my food plots. My corn is not being hit too good right now - the acorns are way too many right now. Heck of a crop this year it looks like.

Remington R-15 .223 REM for predators
I also like to "hunt" sporting clays with my Benelli SuperSport!
