40mm cups of some sort

Not 430 or 433.

These are actual projectile bodies for 40x53SR projectiles along the M430 series (not sure about the exact variant).

The left one has it’s driving band pressed on but not turned into shape.

Thanks. It was close, but not the same to my 430 so I thought it was different. Didn’t think about it being not finished yet.

Very cool!
