In the above drawings,the one with DWM#474 is 9x74Forester(a rare caliber from 1900,not listed in 1904 catalog-per Dixon),it shows a bullet dia.of 9.1mm(.358")Dixon shows it as 9.02mm(.355").The DWM#474A is 9.3x74R,it shows a bullet dia.of 9.35mm(.368"), Dixon shows it as 9.27mm(.365").The drawings seem to be design drawings and the "Dixon"figures are from cartridge collectors measurements.All this illustrates the variation in bullet diameters.The 118,35 mark would support a bullet dia of .358", or 9x74R Forester.However,groove diameter of .362" is closer to 108.49 ga.This supports my opinion that it doesn't make much difference what you call a cartridge, if you can find or make bullets and cases that fit.Also the rifle will tell you what it wants,if you listen to it.
