Biggest frame size for a 20 ga?

[Austin W Hogan]

Dave; John Truitt has it correctly expressed; frame size determines the weight between the hands, not the overall weight. I have an excel file showing this, but it does not fit the 19.5 kb limit.
With respect to the Parker catalog page shown in the last PP. It appears that the Parker catalog writers, and King's shop employees met only at the annual clambake, and then competed on opposing horseshoe teams. The table shows a 10 12 ga two barrel set gun with the 12 ga set up 6 oz lighter; it also shows a 7lb 1 oz 28 inch two frame 12 and a 7 lb 10 oz 28 inch one frame twelve, plus some 1 1/2 and 2 frame twelves lighter than 1 frame 16's.
I'll try to find a way to post those tables. They show barrel swamp, not frame size, to determine gun weight, as John says.
Best, Austin
