Don ... Thanks for posting the information. The 20s from a handling standpoint are a close match to the 12s.

The shell payload of a 2" 12 (7/8 or 15/16) matches the 20. I doubt there is a good way to show the 2" 12 will pattern better than a 2 1/2" 20 with the same payload. I know I wouldn't want to shoot today's 20 gauge (2 3/4") target loads for long in a 5 1/2 lb 20 for very long.
