Some years back I copied this into a spreadsheet from a Shooting Times Mag in answer to a reader's question. Unfortunately, I do not know how, or even if it can be done, to make a spreadsheet line up properly here...It is though I believe fairly well readable. If anyone has other lengths that should be added please post them & I will add them to my spreadsheet. I am only interested in those from US makers. Interestingly while the most popular gauge, 12, had the most lengths available at 7 the 10 & 16 gauges both were only one short with 6 lengths.

Gauges & Shell Lengths From Early 1900s WRA Co Catalog

Gauge Lgth 1 Lgth 2 Lgth 3 Lgth 4 Lgth 5 Lgth 6 Lgth 7

4 = 4"

8 = 3 - 3 1/4" - 3 1/2" - 4"

10 = 2 5/8" - 2 3/4" - 2 7/8" - 3" - 3 1/8" - 3 1/4"

12 = 2 1/2" - 2 5/8" - 2 3/4" - 2 7/8" - 3" 3 1/8" 3 1/4"

14 = 2 9/16"

16 = 2 1/2" - 2 9/16" - 2 5/8" - 2 3/4" - 2 7/8" - 3"

20 = 2 1/2" - 2 5/8" - 2 3/4" - 2 7/8" - 3"

24 = 2 1/2"

28 = 2 1/2" - 2 7/8"

32 = 2 1/2"

.410 Cal = 2"

Later Lengths

10 = 3 1/2" Mag

12 = 3" Mag, - 3 1/2" Mag

20 = 3" Mag

28 = 2 3/4"

.410 Cal = 2 1/2" - 3"
