help identify round
Thanks
This looks like a 50 cal but longer about 3/8".
Where a 50 ends this goes on 3/8 with a double crimp on a black tip.
Head stamp 3B at 12, a star shape at 3, 41 at 6 and a huge primer.
I suspect it a 12.7 Russian but google isn't finding it.
thanks

Sounds like the 12.7X108mm Russian.
Our 50 is 12.7X99mm.0 -
Thanks
I had another 12.7 but it didn't seem quite as long.
And 41 threw me off too.
But could have that ECRS kicking up too.

Like CRS but happens earlier0 -
Howdy MMM,
12.7 x 81-Breda probably too short?
Can you give diminsions? (I'm lazy to convert metric to inch). If wider than 12.7 could jump up to anti-tank gun say in 13 x 92-Mauser?0 -
Isn't it amazin, things are always where you left them but never where you think they were,
Found the calipers. Its 108mm just Seamed a bit longer.
thanks all0 -
ChiCom .51 heavy machine gun. Same basic round as the Russian 12.7, but may have slightly looser tolerances accounting for the slight variation. 0 -
Hi,
What you have identified is a Russian made 12.7 x 108 mm. This cartridge is also known as 12.7 mm SDhK.
Your cartridge was manufactured by the Ulyanovsk Machinery Plant (State Factory #3) in Russia in 1941. The 3B identifies the arsenal where it was made. 3B was used on head stamps until 1943 then switched to just 3. The Ulyanovsk Arsenal has been making ammunition since ~1869. The arsenal also used triangles and X's instead of stars.
Eastern block countries of the old Soviet empire which manufactured this cartridge included: USSR, China, Czechoslovakia, Egypt, France, Iraq, Yugoslavia, North Korea, Poland, and Syria.
Hope this helps.
