30mm APDS

i find a picture where can see a 30mm APDS (but the picture is low resolution)
the projectile look a mk149 2 enlarged to 30mm

i suppose that this round is experimental
and the penetrator would be depleted uranium ?

I know in the netherlands we made a few APDS Test projectiles like that. I have one myself, just never seen a red one only black ones…

thank for your response
i know the black projectile (exist also in 25mm ,same shape as mk149)
but this projectile is orange
it my question ;it a enlarged version of mk149 2 ?
