    I picked up a pound of power pistol, they only had one container left and nothing else to choose from.

    Looks like it will be fine for my .40 reloads. How about .38 and .357 mag reloads. Will it work ok?

    I usually use ramshot zip. 4 grains would be ok for .40 but power pistol suggest 6 grains. Wonder why?

    Power Pistol is a slower powder than Zip so you use a larger charge of PP.

    Power Pistol will work with .38 and .357 you just need to find load data for it.

    Go to Alliant web site for data. I wish I could find even 1# any where.
    It is a little slower than Unique, and a LOT slower than ZIP.

    Check a reloading manual out, then look at a burn rate chart. Slower powders need more pwoder to reach the same vel as faster powders, they just do it with less pressure. Which is never a bad thing.:dunno:
    PP is at the upper end of what I call medium burners; Unique thru AA#7.

    BSA70 "...How about .38 and .357 mag reloads. Will it work ok?"

    Went back over my notes and the only test I ran using Power Pistol was in 38 special, I normally use a 158g bullet for these calibers but I had some 125g PFN bullets on the shelf so this was a "I wonder what this will do" kind of a test... it worked out great.

    38 Special
    Bullet – 125g PFN (Rainier)
    Bullet length – .515” (.357” DIA)
    Powder – Alliant Power Pistol @ 6.7g
    Powder range – 6.1g up to 6.8g (Speer)
    Powder burn rate – #33 (Hodgdon)
    Bullet seating OAL – 1.445”
    Velocity – 38 special = 887.2 fps
    Standard Deviation 38 special = 22.14499
    357 magnum = 939 fps
    Standard Deviation 357 magnum = 23.82307
    Test gun(s) – Smith & Wesson model 10-6 38 special w/4” bull barrel & Smith & Wesson model 28-2 357 magnum w/6” barrel

    The powder it's self preformed fine in this test, burned clean, delivered even power (no bullet tumbling). Although I have not used it in any other test for 38 special/.357 magnum, I have no doubt that it will preform just fine for you. I use Hodgdon's burn rate chart as my standard http://www.hodgdon.com/burn-rate.html Power Pistol is right in the "wheel house" with Unique/Universal/WSF, it acts a bit different but burn-rate wise it's right there.

    Good luck and be safe out there

    PP is a great powder in 10mm. I am sure it's just as good in .40. Start low and work it up. What bullet you using?

    Been using PP for some time for .357SIG, w/ very good results. Don't know about .38Sp. or .357Mag. I've always used 2400 for those.

    I saw handloads.com had some .38 and .357 loads listed with Power Pistol. However just be very cautious with load data like that.

    The Alliant Website has the following loads listed for Power Pistol.

    I've used PP in .45ACP .40 S&W & .38 Spec.

    I bought 5 lbs when I found it during the shortages.

    I'd used BE and Unique before.

    I find PP fine for my needs.

    Alliant data is very good.

    I'd buy another 5 if I could find it.

    >Velocity – 38 special = *887.2 fps*
    Standard Deviation 38 special = *22.14499*
    357 magnum = *939 fps*
    Standard Deviation 357 magnum = *23.82307*

    Not to be a smartass, but look up "significant digits".
    Velocity is 887, if not 890fps for .38 Spl. SD is 22. The numbers and average simply don't support so many digits.
    .357 velocity is OK, but is probably really more like 940 fps with an SD of 24. You would be crucified if you submitted those numbers in an engineering or physics class--been there, done that.

    That took a lot of work.

    PP, if I didn't already mention it, is, for me, the new Unique and has done as well for me as my old stand-by. I just can't FIND any.

    I've developed loads using PP for .357 Magnum, 9x19, .38 Super, and .40 S&W. It's versatile and clean burning.

    Thankfully, when I was down to my last pound, I happened to meet a fellow shooter who was willing to swap two pounds of PP for two pounds of HS6. Now I have three pounds of PP to play with... YES! :cool:

    Hopefully, this powder drought will end soon. But when it does, a new drought involving another component will probably take its place... Frankly, I think these aggravating droughts are being orchestrated by aliens performing a controlled experiment. But then, who really knows.

    I use a Competition Electronics Inc. – ProChrono Digital chronograph w/digital remote control to my laptop, linked to http://easycalculation.com/statistics/standard-deviation.php to obtain my mean & standard deviation numbers. I also note type of firearm used, date, time, weather conditions and any other relevant information I may need. I always compare with factory standards and several of my load manuals or current data available, to make sure I am “in the ball park”.

    I used to check my numbers manually but the setup listed above is much faster than my aging brain these days.

    Frankly, the vast majority of re-loaders have no use for digits .0 and beyond (myself included), thanks for your observations.

    Have fun and be safe out there

    In 9mm, PP seems to have more flash and blast than WST or 231, probably because of the slower burn rate. But you can usually achieve slightly higher velocity with published loads, and anyway the flash/blast is better training for the +P+ I actually carry in the gun.

    I've loaded heavier bullets (>158) with Power Pistol in .357 magnum before. They were fun, accurate, loud, and flashy but velocities weren't impressive. May be better in lighter bullet loads.

    PP gave the fun .357 magnum feel but not velocities. Use standard primers instead of magnum.

    Power Pistol is a great powder. I really like it in 10mm, 9mm and .40 S&W. I wish I had more of it.

    Power Pistol is a flashy powder, just the way it is. Does not have a flash suppressant in it. Even a mild load of PP in .357sig shows a nice fireball on a bright day at my outside range. Want less flash, use a powder like HS6.

    I use PP for all my 9 and 40 now its clean and runs really well for me
    Hard to find now like all powders but I stumbled on to some now and then
    and always grab what I can
