    I use the old fingernail test. If you can scratch with you nail it more likely close to pure lead

    i have a lot of lead i can scratch with my finger nails, but most of it is too hard for me to use in my muzzle loaders. So i get it tested by bne, then sort accordingly.

    I'll guess its Babbitt. Take it to your scrap yard and have it tested using their RFX gun.

    I agree


    No. 3 Babbitt – General purpose high speed Babbitt. Works well with thin bearings of light running machinery with light to medium pressures such as compressors, electric motors, pumps and stationary engine parts.
    – 87% Tin, 10% Antimony, 3% Copper

    I spoke to my buddy who works for Otis he said it's babbit.
    I also found this thread in the archives.
    http://castboolits.gunloads.com/show...abbit-question

    Babbit question: Current #3 babbit alloy has a tin content of about 83%. I have a 7# ingot of Otis #3, which I assume is babbit. It has a BHN 17, which would suggest a high tin content. Is the old babbit the same alloy as the new.

    Answer: It's probably quite similar, there were some standards set that manufacturers had to keep within when they produced a babbitt. Could however be a bit less Sb, as most babbitts have a BHN of at least 23, even some of the lead based ones.

    If you can dent it with a hammer, it will cast bullets.
