If you do not mind a modern inline type, watch some of the auction sites and keep your eye out for a White Tominator or a Knight TK2000 both of them are an excellent inline shotgun able to bust turkeys at 40 yards. If you want a more traditonal style then you have to look for an old smoothbore musket or find a T/C Renegade .54 caliber and get a .62 caliber smoothbore barrel for it...
