One suggestion on felt recoil: Those 16ga barrels are fit to 20ga receivers. The end result is a gun that's lighter as a 16 than as a 20. If you launch the same shot charge at the same velocity from the same gun with lighter barrels, science tells us you're going to feel more recoil.

JR, I don't know if the 16ga barrels are leftover Krieghoffs. They're not marked Krieghoff. They fit nicely on my gun, but the rib knurling is different and they don't have the engraving on the breech end.
