I just acquired this awesome 105MM DM23 APFSDS-T projectile. According to Jane’s, it was made by IMI for Germany or maybe in Germany under license. It has a design feature that I have only seen in other IMI APFSDS projectiles in that it has some kind of ball bearing system incorporated around the sub-projectile dart. You can easily spin the sub-projectile by hand inside the three, ported sabot petals. If anyone knows, I would love to find out what the correct case and primer it uses so I can one day match it up if I’m lucky :-)
