Same powder. Great stuff.
Why would you bring back from the Abyss a thread that's over 3 years old only to incorrectly argue against FACTS? Just because one from 30 years ago doesn't look like the powder of today doesn't make them different. Compare W231 and HP-38 from 1980 and then tell what you see.Today they are the same. I bought a can of hp38 yesterday and compared it with a metal can of 231 I bought back in the 80's.
Completely different!
The 231 I have is a gray flake powder. The hp38 is a black ball powder. The burn rate may be similar but they are different powders entirely. I don't know when they became the same powder with different labels but the 231 from back then is not the same as the new 231/hp38.
