So instead of helping the original poster you decided to turn this into a personal attack, accompanied with lies against "Zero supporting" Hi-Tek and His Drones. Your choice.
Back to the topic:
I have used WW, range scrap,lino,mono,pure... and all kinds of mixes. No matter what my "mystery alloy mix" is, it has some contaminants that prevent proper coating cure unless I clean my bullets by soaking them in HCL overnight.
Here you can see three shiny bullets as cast,the rest have been HCL-cleaned. PC or HT curing is completely different with those shiny bullets,they fail in mysterious ways. Cleaned bullets work great.
If things go wrong it may be a good idea to test-soak some bullets and see if they sizzle and change appearance.
