Well done Greg :thumbsup:
Looks similar in shape to 375 H&H mag, just longer and bigger...

Hmmm, 404 jeffery and 505 Gibbs are both not belted.
Projectile diameter is too small for 20mm... My measurement is around 10-11mm
Going with 10.75x68....
Well, let's start with an obvious one 50 BMG / 12.7x99 ?
But the shoulder angle looks a bit shallow for 50bmg ?
Also, I work COAL out to be around 100mm, case length 77mm ?
