I use my Dad's old Winchester to hunt with because it has a fixed 30" full choke barrel and it patterns buckshot excellent. In the swamp that is what I use often. Because the barrel is so long it is clumsy to carry. I found a used barrel online, 24" with polychoke. Should I keep the choke or have the barrel cut? Can't buy a rifled slug barrel for this gun so a smoothbore will have to do. Probably accurate to 50 yards.
