A three-minute video experimenting with alcohol and automotive antifreeze as potential cast bullet quenching mediums.

Test employed 1/2L each of isopropyl alcohol and antifreeze at room temperature. All bullets used in this test were cast from the same wheel weight alloy using the same equipment and on the same day. Hardness testing was performed using a Lee Precision Lead Hardness Test Kit.
