This came to me without a projectile with a full load of cordite. Was it supposed to have a crimp?
It should have had a wad over the cordite. The British loaded with Cordite or Moddite Tubular (aka M.D.T. - Modified Cordtie, Tubular) installed the wad & then necked the case. So as a guess someone pulled the bullet & dug out the wad to see what was under it. These were taper crimped when issued, not slash crimped, the why you don’t see a crimp. But a careful look at the case mouth might tell the story?
I can se a wee-bit of a remaining taper crimp & the mouth looks a little out of round on one side where the proj. came out. 0300h-0330h in your top photo.
Why such a rough headstamp on this, as if applied by a vibrating etching tool?
I do not have a Blank but my Ball headstamp is normal imprint and has a mouth crimp. The headstamp shown does look a bit rough.
I agree on the headstamp, this is the reason I’ve fish it out of a discount bin, it caught my eye, and I took a gamble for 25 cents. And I lost. I thought I got something special.
Definitely doesn’t look like a GB headstamp. Although I don’t have a 1954 specimen. I have 55 and 56 made .303.
