I just checked the MSDS on HF red and black and they are indeed both epoxy. I didn't know much about the different powders when I bought my first pound of Polyester TGIC and started putting bullets downrange by the hundreds. I haven't had any issues with coating or shooting them, so I must have gotten lucky. Still planning to do the work to see if Titegroup will eat the urethane and if the urethane powder will shoot well....or eat up a barrel...
