Shown alongside a .22lr and .223 for scale.

F'n Huge !?!
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 ?
Going with 10.75x68....
.50 BMG isn't a belted case..
Not 10.75x68 either.
Think bigger :)
.505gibbs?
Nope
oilikon 20mm
Hmmm, 404 jeffery and 505 Gibbs are both not belted.
Projectile diameter is too small for 20mm... My measurement is around 10-11mm
There we go, nice work Greg.
Originally based on a necked up .50 BMG, with added belt. Designed for the Boy's Anti-Tank rifle.
.55 Boys?
fuck it too late
Well done Greg :thumbsup:
Looks similar in shape to 375 H&H mag, just longer and bigger...
Well turn this into a game, carry it on Greg
Did it gets its name from being able to fire it through a line of boys and it would stop in the 56th one?
