Thanks Tom. Was hoping someone else would report their 10g chamber length. Have you measured the bores? We know some early Parker 10s were .800".
And thanks Researcher. You saw the 'before' barrels on my table in Vegas. c. 1900 NPE paper cases were available in 2 3/4", 2 7/8", 3" & 3 1/4".
And regarding the load for which the gun was designed. From the introduction of Smokeless Powder in the mid-1890s, the standard 10g load was 2 7/8" 1 1/4 oz. shot with 4 1/4 Drams Bulk Smokeless or 34 gr. Dense Smokeless. I couldn't find any definitive statement as to the speed (Dr. Eq.) for that load, but I estimated close to 1500 fps. The "Super-Ten" Western Super Speed was introduced in 1926 or 27, still in a 2 7/8" case but with 4 3/4 Dr. Eq. DuPont Oval and 1 5/8 oz. shot. Again the speed may have been close to 1500 fps. If 1500 fps is correct, recoil in a 10# gun would be about 48 ft/lbs 1 1/4 oz. 3 1/4 Dr. Eq. (1220 fps) in an 8# gun = 25 ft/lbs.
