ID of two US 40x53SR TP projectiles


#1

On a Canadian museum website I have found two images of US made 40x53SR (so called “HV”) projectiles.
The caps that are usually crimped on top are not fitted.
As we see the shape of the projectile bodies (solid) is quite unusual.
Is there any information or explanations and diagrams available?

Alex, the one on the right is the Practice w/spotting charge XM428E1.

Fede, the spotting charge is located around that centre pin then?
Is it energetic material or those Calyume light emitters in glass ampules?
