Thanks guys. If a sxs w/screw in chokes becomes available, I'll try the rifled chokes just to experiment. The round ball efforts I've been reading about will probably be my next effort. My hunting buddy has an old Stevens sxs that he's slowly been cutting the barrels back and checking accuracy. It has been beneficial so far and he's using factory loads. I'm not sure of his accuracy findings, but will contact him for info.
