Re: smooth bore slugs.
I would loose the rifled choke if I were you. I would just use the mod or improved cylinder that you have.
From my very limite field trials sluggers should do ya fine in woods ranges (up to 50 yards at most). After that you will need to experiment some.
Both my slug barrels are rifled. Kinda wish my barrel with open sights had a smooth bore as it would fill the need I have for an open sighted shotgun. I will have to shoot high $$$$ sabots from it.
Hate to say it but you will have to burn some powder out the big guy to know. I'm guessing you already knew that?
The biggest thing is the type of sights on your gun. I started hunting with a smoothbore with a bead sight. Dad wouldn't even let me see where it would shoot as he said it didn't matter with my setup. As much as I love my dad he was wrong.
Nothing wrong with sights you clip on the vent rib shooting slugs. will work fine at woods ranges.
I would buy several different brands to start out with. All I can say about that is to go to a place that sells them, and buy a few boxes.
BTW, my brother shot a nice 8 point in self defence with my original setup with sluggers in a 20 gauge. That's a funny story for a different post though.
