Insert the usual disclaimers here: Use these loads at your own risk!!!

Looking it up in my "everything 9mm" loading book, I see where Winchester is listing the following for 9mm 124 gr FMJ:

Powder: 231
Primer: WSP
OAL: 1.169 max
Start charge: 4.2 28800 PSI 1005 fps
Max charge: 4.5 32700 PSI 1060 fps

Now, knowing that 231 and HP-38 are one and the same powder, I looked at what Hodgdon has listed for their equivalent load, based on a 125 gr Sierra FMJ:

Powder: HP-38
Primer: CCI 500
OAL: 1.090
Start charge: 4.4 24600 CUP 1009 fps
Max charge: 4.8 28800 CUP 1088 fps

In the same book, Sierra has a listing for 231 in their 125 gr FMJ as well:

Powder: 231
Primer: WSP
OAL: 1.090
Start charge: 3.9 ? pressure appx 900 fps
Max charge: 5.1 ? pressure appx 1100 fps

Speer has the following listed for their 124 gr JSP:

Powder: 231
Primer: CCI 500
OAL: 1.120
Start charge: 4.0 ? pressure 887 fps
Max charge: 4.5 ? pressure 998 fps

Never having loaded this powder with that weight of jacketed bullet, I can't vouch for any of the above loads. I HAVE loaded this powder with 115 gr jacketed bullets and had good results. I HAVE loaded this powder with 124 gr LEAD bullets with good results.

And of course (repeating myself just to be safe), the usual disclaimers apply -- use these loads at your own risk!!!
