So, are HP-38 and W231 really the same?
I'm almost out of W231, and I just got about 4-1/2 pounds of HP-38. I'll be using it for .380 ACP, 9mm, .38 Special, .40 S&W and .45 ACP. Whatever recipes I use, I'll be working them up fresh from starting loads, if for no other reason than the fact that it's a new batch of powder. I have two questions, though:
1) As I look through my load manuals, can I use recipes that call for either W231 or HP-38?
2) Would it be okay to dump my last four ounces or so of W231 into the HP-38 jug and mix it up well before I start working up the new loads? Or should I use up the last of the W231 separately?
