I have a light 12ga from the 70s , the new 16ga and have shot the old 20ga. There are weight difference not only from gauge to gauge but from time of production. When I was younger I could carry the older guns and handle their recoil ( barrel moving backward to reload old inertia system) now in my 70s and planning to hunt for as long as I can, I need the lighter guns after boots on the ground for over 5-8 miles in the fields. So the new A5 is my new way to go. I am planning to add the new 20 ga here soon. That will complete my collection and I will hunt with the 16ga and 20ga.
The 12ga will be my blocking gun since I do not block very often not my hunting style. I now enjoy hunting behind my GSP s and taking only a few birds rather than going after the kill. Some day I will add a citori 28 ga for those time I visit my son in the south for quail hunts. Truly a Browning guy.
