With today's ammo and components, a gun with no choke or "cylinder" is probably more useful for upland than a full choked gun. Shot is rounder, harder, wads are better designed, and the ammo just doesnt need alot of choke to make great patterns out to 30 or 40 yards like it did 50 years ago. Past 40 or 50 yards, any gun basically has a cylinder choke anyhow.
