What Rocketman recalls may be true for felt wads - no way to tell.
For plastic wads in identical loads in identical guns the answers would be: no, no, and no. Shotguns don't duplicate data very well anyway. The slop in the average load would overwhelm whatever diff there may be from the gun, if there was any.
And for a person to perceive the difference, of which there is none, it would require a nervous system so advanced beyond the current model that it won't be a problem for some considerable time, if ever. Of course that doesn't mean that there will not be people that will swear to the converse of any or all of the above. There are also people who attest to the tonal difference if the phase is reversed in a single speaker. I'm sure they also ride their flying pig to work.
