You know, just because someone doesn't agree with the theory why something works doesn't negate the fact that it does work.
Hashing through this over and over and over again, I seem to have gotten new insights. Here's what I got: the key point being (short arbor gun) that if the wedge was driven in farther, the barrel would move back closer to the cylinder.
So here's the cause and effect - the bullet tries to tear the barrel from the frame. That force hammers the wedge which then recoils causing the barrel to move towards the cylinder - since there is play in that direction and it can bounce back. Who knows how many times it bounces (vibrates)before the oscillations end? That would be a good subject for high speed photography.
Fixing the arbor depth removes that play, so no oscillations. No way to bounce back. The only wedge wear after that would be from the initial force of bullet hitting the forcing cone and sliding through the barrel. But that's not a sudden hit like whacking it from a distance with a ball peen hammer. If there was a gap, it would get hammered, otherwise it's more of a hard push.
