Paul: p. 202-203 of Major Sir Gerald Burrard's 1947 Second Edition of The Modern Shotgun, Vol. III “The Gun and the Cartridge has an extensive table of loads. Unfortunately, he lists 33, 36, and 42 grain powders, along with Ballistite and BP. I ASSUME the 42 grain powder is Schultze Bulk (42 grains = 3 Dram), 36 grains is "New E.C. (Improved)" Bulk, and 33 grains is Imperial Chemical Industries (Eley & Kynoch Cartridges) Dense Smokeless Diamond powder.

He lists 10 different 8g loads. The 'standard velocity' 4" case uses 72 grains of the '42 grain powder' and 2 3/8 oz. shot, or 7 1/2 drams BP with 2 1/2 oz. shot.
