.950 j.d.j

[orcutteod]

Recent pickup here with this .950 JDJ round which is about 24mm in diameter. For all intent and purposes this is a cannon round produced by SSK Industries. They only made 3 rifles to fire this round and have stop making ammo for it. Also enclosed is a side by side comparison with a 20mm Vulcan and a US 25mm.

Another pic comparison with the 1 inch Nordenfelt. The JDJ was made from an 20mm Vulcan shell. Anyone know what the R stands for on the shell case?

In the collectors world it usually stands for “Replica”.
