Last Sunday and today, this Sunday, I did a little casting and powder coating. Something odd though and I’m wondering has anyone else noticed the same thing.
So, I warmed 3 handfuls of 125 9mm. Then I tumbled in Gloss black powder, which gave pretty good coverage the put them in the oven. But the next 3 handfuls just would not cover in the Gloss Black. Useless, in fact and bad enough to discard.
Today, the same thing. First batch gave good coverage, second batch useless.
Has anyone got any observations?
