Me I have and love SxS. My AYA #2 in 2 3/4" 12 ga double trigger will handle most of what I shoot in upland (ie pheasants 1 1/4 oz #5 nickel plated shot; sharptails 1 1/8 oz #6 magnum shot; huns and chuckars 1 1/8 oz #7 1/2 magnum shot; quail and doves 7/8 to 1 oz #7 1/2 or #8) etc.
Rabbits and dusky grouse a 20 ga Fox SxS double trigger cut to 21" cylinder choke loaded with 1 to 1 1/8 oz #4 or #6 shot. Butt heavy, thus it swings on extremely fast for dense forested areas and is great for "snap" shooting.
Turkeys I use a Rem 870 with a 21" barrel with full choke inserts and Bushnell Holosight. It's loaded with 3" mag 1 7/8 oz #5 copper plated shot. This is a very specialty gun.
Ducks usually a semi auto (less recoil) 30" barrel with #5 Kent Tungsten Matrix shot.
Geese again semi auto with #3 Kent Tungsten Matrix shot.
Doves...well for fun I limited out once with a SxS Winchester 21 in .410 within 1 hour of daylight. But I wouldn't recommend a .410 for anything other than snakes.
I also really like pheasant hunting if not walking too far with a Merkel drilling...12x12x.243 under. This is double triggered and choked modified and full. It is about 7 lbs and is great when a coyote comes up out of shotgun range...ie the .243 comes into play.
Me I like double triggers only because they are much easier to decide on which choke to go with. Single selective triggers just don't work as well, nor as fast.
Oh yes and if I feel masochistic or nostalgic and want to carry a heavy gun which absorbs recoil, it is a 1950 LC Smith, "Elsie", SxS 12 ga 2 3/4" loaded with one of the above upland loads.
The 12 gauge is absolutely the most universal shot shell available without a question. If you don't reload, you can buy loads from 7/8 oz to 2 oz (3-3 1/2" loads only). It can be had in not only lead, but soft lead (cheapest loads) to hard high antimony copper or nickel plated, buffered, tungsten matrix, bismuth, steel, Hevi-shot, and who knows what all is out there on any given day. You can get excellent deals in the fall before hunting season starts.
20 gauge runs a close second for availability and cost, but has never been known for the best patterns.
16 gauge is a very good upland shot shell, but is expensive and loads are very limited.
28 gauge is great for doves, quail, rabbits and dusky grouse. Again limited loads. OK for put-and-take early season pheasants and chukars behind a dog.
What ever you get, you'll be happy I'm sure if you only get out and use it as often as possible. It's that time of year!:wings:
