Unknown round

Hi, does anyone have any idea what this is? 40mm across the scabot. Regards Dom

It looks very similar to a 40mm armour plate test projectile. These were fired at plate by means of an enormous air gun. Used, I believe, at RARDE Fort Halstead. I have a drawing, but not to hand.

Eggburt maybe familiar with it

I think there was an enclosed (tube) 400-500 m long special (then) RARDE-run test range facility on Foulness, but I had nothing to do with it. I just used to see it when driving past.

I think it was present on what was originally the rain fuze sensitively testing facility, which was used well before I worked there? The facility being a series of rain (precise sized water droplet) producing frames through which a fuzed, but inert projectile, was fired.

I've seen (worked on) larger 40/70-based special rounds for subscale APFSDS testing, but that's all.

Thank you. It appears to be in a Bofos shell case and the projectile is incredibly heavy for its size. Would it be depleted uraniu?
