16 in 50 Caliber Smokeless Powder Pellet

I watched this video (https://youtu.be/Ywb2XoNY4C0) on the propellants used on the large caliber guns from the US navy and I wanted to print some just cause I think that’s cool. 

I’m fairly confident in the overall sizes of them as that was consistent from ship to ship for the later designs of large caliber guns however the hole spacing may be slightly off from what was used in a specific ship as it changed on the size of the guns and the specific gun. The pellets were neatly stacked and added into 110 lbs bags of which 6 were used for a full power shot. Reduced number of bags could be used to increse barrel life. 

You can see a standard size sticky note for scale.
