My Russian gun shoots great and the barrels ARE side by side. I can't speak for all of 'em, but it takes birds about as far away as my single barrel repeaters do. It tosses a slug about 5" left at 50 with the right barrel, same to the right for the left barrel and dead on elevation. That's about normal in my experience with side by sides.
Okie, steel has come a long way in the last 20 years. And there are some options out there better than lead if you can afford them. Hevi-Shot has introduced a line of ammo called Classic Doubles that is supposed to be safe for older firearms. I plan to try some in my 16 ga Model 12 this next duck season. I love the sport so much I would hunt 'em with sticks if that was all we could use. Dust off that 311 and dig the decoys out of the dump.
AMEN brother! How the HELL could I grow up on the Texas coast in the marsh and not love duck hunting? Impossible. I love the sport and don't really pay much attention to the tools I do it with so long as they shoot straight and hold up. If I have to go out there and throw rocks, I'll adapt. I'm poor, so hevi shot is only for the occasional goose hunt. Steel works fine over deeks for ducks.
I started duck hunting at age 14. I'm 55 now, so 41 years I've been doing it and I don't plan to stop until I'm in a wheel chair and I might find a way even then.
I figure if someone is too pansy to get wet hunting or too cheap to buy a steel shot rated gun, hell, that just takes some of the pressure off and leaves more ducks for me.
I was even hunting 'em when about everyone else quit back 20 years ago when the hatch got low because of drought and they lowered the limit to three bird. One morning, I set up, birds everywhere, right at shooting time two blue wing teal flew in and crossed just as I fired and I knocked 'em both down. 5 minutes later, a widgeon few over and I popped him. Limited 25 minutes before sun up, was in the truck driving home as the sun rose. LOL! At that point, I began to wonder if getting up that early was worth it, but I kept hunting anyway because that's just who and what I am.
