Building up a little ammo collection and I've got these 4 cartridges that have no caliber markings.
Cartridge on the left is a .22 for scale.
Not sure on age or anything other than they are stamped, from left to right; D, H, D, U, H.
Bullet diameter from left to right is .220 , .223, .217, .312, .375.
Intrigued to figure out what these are.
