Mystery Powder in 9mm Luger 147 gr load

[martinga111]

I'm trying to identify this powder I found in some hand loads I recently obtained. If they shoot well. I'd like to duplicate the load.
See attached photo. The flakes are light green in color. about 1/16" in dia. Not sure if they are super short cut stick or flattened ball powder.
I measured 3.8 grains in a 9mm Luger case with a 147 grn plated TMJ-RN bullet

I know it's not Unique, Power Pistol, CFE, IMR4895 or H4895 IMR3031, IMR4064 IMR4227 WST, Red Dot or Reloader 15, because i have all those and none are like this.

It's not an SSC powder for sure.

Kinda looks almost like a shotgun powder being the shape it is? Maybe someone with half a brain will chime in.

Contact the person you got the loads from, cause an improper guess from one of us yahoo's could lead to injury.

There's the half a brain. Go with that answer

Not a good idea to identify a powder by looks.

That said it kind of looks like clays but the pic is out of focus.

Why are you shooting someone else's reloads in the first place?

And there is the other half a brain.

Looks like a Maxam powder, perhaps CSB-1, I use CSB-1 3.8gr at 1.130 with a MG 147gr fmj in my 9mm loads. Works well for me very consistent.

It does look like one of them for sure.

That said, I'd NEVER load a powder that I didn't know exactly what it was.
