Interesting thread
http://www.shotgunworld.com/bbs/viewtopi...cbb5792e1f04003I have not seen E.C. No. 3 specified for smokeless proof, nor do I recall loading data marked on a Belgian gun
Raimey did most of the deciphering, and more educated thoughts would certainly be appreciated!
Bore 17.0mm = .669”
Right choke 16.9mm = .665” = Improved Cylinder
Left choke 16.4mm = .646” = Improved Modified
It was proved with E.C. No. 3 : "New E.C. (Improved) No.3” was introduced in the U.S. in 1904 and was 11 grains = 1 dram equivalent; 33 grains = 3 Dr. Eq.
Pre-1924 16g service load was about 1 oz. / 2 3/4 Dram (1220 fps). (4.9 grams = 75.6 grains = 2 3/4 drams)
Load markings??:
81 may be grains of black powder = 3 dram
50 “plombs” (weight) may be 4.9 gram Bulk Smokeless powder = 2 3/4 Dr. Eq. (50 grains = 3.24 grams so that doesn't work)
24 is likely grams shot (about 7/8 oz.) OR 24 grains = 3 Dram Eq. of Ballistite Dense smokeless
