This buck was shot in my home town. I don't think ARs played a part in this. Every acre is posted and most is suburbs. 99% of the deer around here die of old age or auto collisions. This guy was lucky to have permission. I shed hunt down the street from my house and have found a 5 point side and a 6 point side.
Upstate, however, where hunting is more widespread, I've seen a big difference. Bucks in the 200lb + range are becoming common. Last year, guys I knew shot a few deer that went into the 150s. We have the genetics. Just need age and nutrition.
