If the barrel is marked for 3 inch magnums, yes. Marked 2 3/4, no.
Yes your Winchester model 1897 pump action shotgun can shoot buck shot through it.
If it's chamberd for 3" magnum shells and the owner's manual says so.
Yes you can. Lead Shot is Lead Shot. I shoot all kinds of different sizes of shot out of my Mossberg and Remington Shotguns. What you do not want to do is shot a slug out of barrel made for shot. Get a rifled barrel for that.
You must follow the instructions in the owners manual or call S&W
No.
Yes, you may shoot slugs or buckshot through a shotgun fitted with the C-Lect Choke system. This is from the tag that Mossberg attaches to their shotguns fitted with C-Lect Chokes.
yes
Yes it will shoot slugs and buckshot, some use them as a deer gun.
Yes.
You can, but, it will not be a good thing.
The mossberg Model 88 maverick can definitely shoot slugs and with fair accuracy too with the un-rifled stock barrel. Try the Winchester Super X 2 1/2 inch 1 oz. But hang on to it or it will hurt you. The recoil is roughly doubled.
Yes
