I’m not sure how to measure this….

[Robert]

EDIT: I did a test pour and mic’d the result at .357″ x .6875″
​
I picked this up super cheap but I’m not 100% sure of the caliber. Does anyone know how to properly measure it?
​
Also, I can’t find any other examples like it for sale on retail markets (ie, pieces that are made of solid hardened steel). Anyone know where to get a brand new one?
