Tatume,
I would just enjoy the gun as made, a shotgun, and leave slug and/ball shooting to guns with barrels specifically designed for that use. I inherited Uncle Ray's (on my wife's side of the family) LC Smith, a 1910 vintage field gun with beautful damascus barrels and bushed strikers. I promised my Fatherinlaw to keep the gun in the family and I will. I intend to use it as Uncle Ray did, on his North Dakota farm, on pheasent. LC's are nice old American guns, I would love to see a photo of yours.
