I copied this from the Ceaser Guerini site someone linked to:

"The DuoCon forcing cones are a unique dual conical long forcing cone system designed by Caesar Guerini to produce optimum performance and maximum versatility. The first conical section maximizes chamber pressure and permits the use of fiber wad ammunition. The secondary 4.5" long forcing cone section reduces recoil and increases pattern uniformity."

It is interesting that we again get to GT Garwood's contention that gas bypasses the fiber wads in a long cone. I added the underline and italics
