Biggest frame size for a 20 ga?

[Austin W Hogan]

I think Kevin's brother was researching Hedderly in the 1990's, but never published the article. Hedderly was ahead of WW SuperX putting 8 gauge loads in 12's and 10 ga loads in 20's.

Dave ; I merged and printed the files, then scanned them for jpegs. The first shows two two barrel set guns; the 12 is 6 ounces lighter than the 10 on 56553; the upland barrel is much lighter on 73201; it makes up to a gun a half pound lighter than a 1 frame of the same barrel length. The difference in filing can be seen in the tabulated data.
The second shows two 1 1/2 frame twelves lighter than a 1 frame 16. The 6 lb 8 sixteen is a result of filing the swamp in the first four inches as the table shows.
