Gentlemen,
In the Pigeon Ring era one could purchase commercial loads for a 12 bore of up to, if memory serves me correct, 3 and a half inches. The extra length was for additional wadding, NOT additional shot. The additional wadding served to soften the blow from the wad onto the shot. This produced LESS deformed shot and subsequently better patterns.
The modern 3" magnum was introduced as the Super X Winchester. The Suer X 3" was made for/in conjunction with the Super Fox HE. I think they were both introduced in 1923. I might be a year late on that... How about one of you guys Google it an let us know?
