Milled powder, still bad results.

So I milled the powder from before, 5 hours. The burn time on the powder is still… bad. It’s very much as powder as powder can be. But it still just burns. I’m wondering if the scale I got measured the ingredients wrong. I made a new batch today and will mill and try it out tomorrow. Till then, here’s a video. Any ideas cusswords or comments welcome. I wonder if the powder is meant to be… that grey. Again this powder is serpentine, so it is a dry mix.
