site. Don't think for a second I could come up with this.

This one single sentence pretty much says it all that a lube needs to do, and I think you are seeing it with your jacketed bullets experiments.

An effective cast bullet (or in your trials jacketed) lubricant provides a fluid film barrier between bullet and the barrel during the firing event, leaves the surface of the bore the same condition shot to shot, (maybe what you are seeing in your tests) and completely departs the bullet at the muzzle to prevent balance disturbances farther down range.

I think your Alox lube is probably helping to stabilized the conditions of the barrel.
