I am not quite sure but they might be Boyd's .55 anti tank rounds that were used by Britain early on during WW2.

I suggest someone made up a dummy for display. They look to have used a solid hunting bullet. One I have here is marked K43 WII and the other is Dominion Arsenal. The bullet measures .565 at the mouth. I'm sure that's what you have.

Its a round of .55 Boys Antitank rifle ammunition.

Kynoch, 1940, .55 Boys' Rifle, Armour-piercing Mark II; it's all on the headstamp.

Odd bullet, though; my W-II has a pointed slug.

Interesting cartridge, based on a .50 Browning case with an added headspacing belt. Opening out the mouth enabled them to run hotter loads through it; as it finished up, it carried 44% MORE energy to the target than the parent round. I have absolutely NO idea why somebody didn't run these in the M2 Browning; would have made a much better gun.

Original Boys Rifle ammo is rather pricey stuff these days; $30 a shot is low. For people shooting the thing, I have no idea why they don't just solder a belt onto .50 Browning brass.
