7.62 x 54R UXG

I have been unable to find any info of the manufacturer of this, Grey, steel cased Drill/Dummy round , it has 3 long tapering flutes, GM bullet, brass primer with 4 stab crimps ,headstamp is, 63 UXG made in 1963, but who is UXG ? thanks Randy

If you flip it around, does it read ‘bxn’? If so, it is Czech.

Before even looking at the headstamp, which should be read as “bxn 63”, the tell-tale long, tapered case grooves and the 4x90 degree primer staking identify this as Czech.


Thanks gents, yup thats it , bxn its very small and right on the rim, it sure does help to turn it around as well. Randy
