10.67x58mmR Russian Berdan, Photo Showing 3 Flash Holes In The Primer Pocket

Photos from GUNS.RU forum posted by forum member “shtil” of fired 10.67x58mmR Russian cartridge cases. Some of the cases are missing the primer and one can see the 3 flash holes spaced 120 deg. apart in one photo.



The use of 3 flash holes was typical of UMC production in the 1870s and later for military caliber black powder rifle cartridges and was followed by other manufacturers following UMC practice. Jack
