Interesting! Folks have been using Epoxy as a bullet "lube" for around 50 years, I think. I have some old test reports somewhere that were very positive. I would guess that the epoxy Bayou uses has Boron Nitride added to it. Coated bullets reduce lead exposure, which is especially important when shooting at indoor ranges, Doubly important if you have small children around where you reload.I have been using 4.0 grains of Bullseye with the Bayou Bullet 200 grain SWC lately and find it very accurate. I can get the powder coated bullets in green, red, and yellow. I use different colors of bullets when trying a new load or loads for different guns of the same caliber. So far the guns have been easy to clean, no mess while reloading, and no smoke when shooting.
