i've run out and no one on the northwest side has any but carter's has two others that they asked if i could substitute. i've only used 231, universal clays & power pistol.
i'm trying to keep the velocity about the same. suggestions? while searching i did see(and remember)about PP(which i have a couple of cans of). tia |

Why is 231 so hard to find? I use it for practice ammo. But I don't find it to be so wonderful that it should be sold out everywhere.  Good question since I have not seen any in months either. Maybe it is because it is that bad and only old guys still use it?

I went to HP-38 its almost the same ....I think its better because it is not temp sensitive like 231 . You're saying if you put the same powder into a differently labeled can it ceases to be "temp sensitive?"  Come on BK1 I am sure you can decipher my illiterate posting's by now LOL !!
231 and hp-38 have almost identical burn rates .....I have found that on very hot days 231 tends to spike up but HP-38 does not |

I read numerous places that W231 and HP-38 are the exact same powders in different containers but then it seems every burn rate chart I've seen has them listed a few places away from each other. What's the explanation for that? Probably the charts are wrong. Go look up the latest load data on Hodgdon's site, the HP38 and W231 loads are IDENTICAL. Same powder, same pressure, same velocity. |

One has to remember that St Marks Powder in FL is the chief supplier of ball powders to Hodgdon be it H series or Win Series. Production runs are scheduled and as such Hodgdon gets what they get when they get it. I have not see 748 in a few months, and there are larger sizes of 231 out there ie 4 and 8 # jugs. Hodgdon does not make powder and as such are at the whim of General Dynamics in FL for ball powders at St Marks and in Canada for stick powders for the IMR powder lines for the most part. ADI supplies the extruded powders for Hodgdon ie Varget.
If you go to the Hodgdon Web Site and look at the MSDS sheets you will see that SMP231 is the same as W231 and HP38. And there other twins in the line up, too.. |

thanks guys. Derek, the guy said he had WST and something else but all i can think of is wtf & i know it's not that! on WST, are the numbers(4.3 of 231) similar? i plan to look it up & work it up but just asking. I use WST for 45acp loading with lead, ran out the other night, stopped last night and found my local FFL had more in stock. WST and 231 will almost mirror for data, but work your own loads.. 5gr WST behind a 230gr RNL RCBS molded from wheel weight gives me 950fps from a 10" UZI barrel. |

The charts are not wrong. My chart has them very slightly different. The difference is testing from different lots. HP38/231 are the only ones that shows even slight difference. The others that I have bothered to look at are identical. |
