All of the statements above have taken care of my opinion on the matter:
You can't figure it out by disassembling a cartridge.

But, for giggles...

.22 WMR
Winchester "Supreme"
36 gr HP
6.5 gr unidentifiable (super fine) ball powder

Interestingly...

.22 WMR
Winchester "Supreme"
30 gr HP
6.5 gr unidentifiable (super fine) ball powder

Same powder charge, but a 20% difference in bullet weight.
That powder is highly unpredictable, but seemed to be identical during my experimentation. The (seemingly) same ball powder can be found in the 40 gr (45 gr?) Dynapoint "HP" load, with a 5.6 gr to 6.0 gr powder charge.
