First of all, several burn-rate charts show HP-38 to be faster than W231 with several other powders in between them. However, since burn-rate is partially controlled by an inhibitor applied to the powder or by how much the ball powder is flattened, I suppose that the same powder could then have 2 slightly different burn rates.

Personally, I have loaded both powders extensively and will say that W231 does not look like nor feed through a measure like HP-38. But again, I have read too that graphite is also added to prevent caking and help with flow. JMO.
