My point about the more gradual taper is that a longer forcing cone would HAVE to be a more gradual taper, the angle would have to be less in order to make the cone longer, wouldn't it?
Point about steps and double tapers is that nobody makes a forcing cone with steps or double tapers, do they?
Point about the "diamond marks" on the chokes struck me as silly as saying Browning decided to call the gun a 625 because they discovered a "625" on the underside of the receiver.
If the bottom barrel on an O/U having the underlug forged as an integral part of the barrel makes it of "chopper lump" construction, then we should probably add my question to the stupid list.
