I’ve had these cores for some time now and i am unable to identify what they came from.
The thing about them is that they are very light. below you can see a standard Core from a 20x102 projectile on the left… that weighing close to twice as much as the other 2. does anyone have an idea what they came from and what they could be made of?
Length is 49.31mm for the capped one and 48.65 for the solid.
both are 12.96mm wide.
thanks already, experiment
