Found this item in a $1 bin at the recent Kansas Cartridge Collectors show.
Shown below is a 6.5 x 50mmSR Arisaka cartridge with a black wood bullet, unstaked unstruck varnished brass primer , NO knurled cannelures on the case and NO hole drilled in the case wall. Cartridge weight is 12.87 grams or 198.6 grains.
I could not find this cartridge in Japanese Ammunition 1880-1945, Part 1 by Ken Elks.
So is this a dummy round or a blank round?
Any information/discussion most appreciated.
