I think bigger racks are being produced for two reasons.AR/less deer more food.On public lands there's very few buck being killed and there are a few nice ones but it's hard where overharvests occur.
I started practing my own AR before it became law{personal choice}
Having said that in the long run it won't be good for hunting as the license sales will reflect the lack of deer on public lands.
Where there is some control of the harvests I think AR is working well.
