Burrard's The Modern Shotgun Volume 3, page 208, has a table titled "Loads for All Size of British Cartridges" and in ten bore shows 3-1/4", 3", 2-7/8", and 2-5/8". Another table on page 320 "Proof and Service Charges for Different Gauges" lists the same lengths for the ten.

This edition was published in 1932.


I am glad to be here.
