I hauled both of my Dad's old auto 5s home last weekend, he passed away in April, one is a light 12 the other a heavy magnum, both have killed more than their fair share of birds. 30 years ago I tripled on roosters with the light 12. As far as I'm concerned in firearms manufacturing/design the boys are still chasing John Moses Browning, the man was pure genius and he hasn't been matched.
