I don't have to contact them. I can look at the data. You're the one with your head in the sand.

If they've always been the same powder then explain this.

45 ACP200 gr SWC
231 4.5-5.0 gr, 719-811 fps
HP38 4.5-5.0 gr, 808-892 fps


I'm not saying they aren't currently the same powder. But at some point there was a difference between them. That's about a 12% difference.

The currently manufactured powders are indeed the same, but there are likely still some canisters of the older powders still floating around out there; especially the larger size canisters that take a long time to burn through.

bds, what is Hodgdon's 40 S&W barrel groove diameter? Please point me to that information. Maybe it's the same.

THR is just another online forum and I am just another guy on the internet.


Me:

Good morning,

Your online load data doesn't show groove diameter of test barrel.

What was the groove diameter of barrel for 40S&W pressure testing?


Hodgdon:

Hello XXX, Thank you for reaching out to us.

SAAMI list a bore dia .390 and groove dia .4005 for the 40 s&w.

Thank you

Do you accept that they are currently the same powder?

I do believe I've stated that at least one in this thread.
