    Name that cartridge.

    Lunchtime puzzler for some of you, name the cartridge in the following pictures.

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

    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 ?

    .50 BMG isn't a belted case..

    Not 10.75x68 either.

    Think bigger

    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.

    Well done Greg

    Looks similar in shape to 375 H&H mag, just longer and bigger...

    Did it gets its name from being able to fire it through a line of boys and it would stop in the 56th one?
