Title: Re: Two Things I Learned Yesterday Post by madsenshooter on Aug 7th, 2018 at 5:20am
An interesting tidbit I learned about babbitt's came from a late 1930s patent. Seems adding tellerium, a byproduct of lead smelting, makes a babbitt alloy that will work harden. I size my bullets down in steps to give the bands a bit of that work hardening. I don't know what all brands might have tellerium added though I suspect it became a standard practice to use it when the patent expired. Work hardening babbitts may have played a significant role in the war effort. Rich, genuine babbitts are tin based babbitts and have a very high percentage of tin.
