For deer slugs all the way. For social encounters 4ought buckshot. With the slugs I have an old wingmaster with slug barrel with rifle sights. With the buchshot an old wingmaster with 20" bbl and a big brass bead, that particular shotgun was one of the police turn in shotguns thing it cost me $200. Stripped the stock, used a sealer on all exposed wood, inside the forend and on the buttstock. About 4 coats of true oil came out nice id I do say so. Frank
