Help needed for Unidentified 30mm Projectile

Hope someone here can help with this as I'm unable to identify what looks like a 30mm projectile.

Measurements taken tally quite closely with RARDEN projectile calibre, but the construction of the body appears to be aluminium and the nose is definitely aluminium. The body is machined with a recess for a press fit trace element and a cavity for explosive filling or dummy filling.

The nose is aluminium and threads onto the body but also has an internal profile with thread in a manner that could possibly accept a fuse assembly for HE, I guess. The projectile has no wear and has certainly not been filled or fired.

Body is patinated in light grey/silver finish giving a mottled effect I have never seen before. The driving ring is asymmetrical in profile similar to the French made 30mm and some British RARDEN rounds. The profile of crimping recess behind the driving ring is a chamfer rather then a circular profile found on most British 30mm I've seen before.

The pdf file I've attached gives the full drawings, detail and dimensions of the projectile I've got. Hope someone can enlighten me as to what the hell it is, as it's been bugging me for months. Cheers.

It look very similar with the 25mm TP-T SR we used on our AIFV
TP-T SR for Target Practice-Tracer Short Range.
On shooting, by inertia, the aluminum nose enters the body, letting the air penetrate into the body and strongly braking the projectile. It allows shooting on reduced shooting ranges, between 200 and 500 m (for our 25mm).
Look on the doc of our 25mm TP-T/SR

Took a while to get the translation right, but my unknown projectile has a fixed, threaded hollow nose which is screwed firmly into the body into which could be placed a charge or filler. The documentation for the TP-T SR round that you kindly attached clearly, (Once my French was clarified with Google translate!!), is a reduced range training round, by controlled inertial expansion of the outer body of the projectile increasing air resistance thereby causing the gun to fire ballistically (near) identically to the service round, while as soon as it leaves the muzzle it behaves with a scaled down matching trajectory at a reduced range.
