I put the cylinder bore in the left barrel for the rear trigger. Front trigger is for small game, mod choked is my thinking after doing some patterning and duck/dove hunting with it. It'd reach out there on squirrels well enough. IC would be better for rabbits, I reckon, but I have killed a lot of rabbits with a full choked .410.
I contacted a smith about the swivels, too. Great to have swivel studs on a gun for waterfowling. Up til now, I've been using a slide on deal, but just for carrying. It would get in the way shooting it. But, I always remove the sling before shooting ducks, can catch on marsh grass, reeds, and stuff. Would be handier in the woods, for sure, with swivel studs and I'll get that done I think. I installed my own on my Rossi 92 carbine (barrel band comes off), but I'm a little scared to drill into that barrel rib, LOL.
With slugs, the right barrel shoots a little left and the left barrel shoots a little right at 50 yards due to the barrel regulation, but it's easy to correct for. It sort of limits your yardage, but I plan to do some more experimentation on sight picture with it, maybe get 75 yards out of it if I can. 50 yards can do the job, though, especially on hogs which you usually run into up close. Just adds to the versatility of the gun as a general woods gun.
If you're camping, it'd be good to carry for bear protection, too, slug in one barrel, 00 in the other, though mine is in 20 gauge.
