I'll start by stating mine. For waterfowl I like a pump and have been shooting the same Remington 870 for 50 years. Also served as my bread and butter gun for all purposes before I could afford to buy more. For Pheasant hunting my choice is a 12 gage O/U. Currently using a Beretta lightweight. For northwoods Grouse hunting I prefer a 20 gage. Used to go with an 870 in that caliber but several years ago I popped for a CZ Ringneck SxS. that I've been very happy with. 26" barrels make it short and light which I appreciate going up and down hills and thick brush in my old age. The reason I prefer doubles for upland game is because I feel they are a safer option when working with dogs in the field. Break open the action and you've pretty much rendered it inert while dealing with pups, picking up game birds and climbing over obstacles. That's my story, what's yours?
