    Well.... been mainly shooting 38s rds in my S&W 19-3, 6" barrel .357..... But have some Special loads of .357 from a buddy (he has long since passed away) no clue the stats of the .357 loads but MAN they pack a punch....

    Now that i load alot of .223 really thinking about .357 loading now...

    I shoot more 9mm but they are so cheap to buy... not sure if I will re-load them... But .357 is so POWERFUL and Fun.... re-thinking my loading options


    any input on Powder that would work well for Both, and any incite on Loading .357 would be great... powder...Bullets.... etc.... i should have around 400-6000 brass currently so pretty ready to roll......

    Oh and its a Lee pro 1000 press


    Thanks guys

    Unique will work very well in 9mm and pretty well in .357.

    It will not give the top velocities a slower powder like 2400 or H110 will in the .357.
    But those powders will not work at all in the 9mm.

    It will do well enough to let you know you are shooting a .357 though.

    I have used power pistol in both my 9mm and .357mag loads. It seems to be very accurate but I don't like the brilliant flash that power pistol delivers with heavier loads.
    You will actually loose sight of your target for a moment.

    I also use titegroup and universal for both of these calibers as they will meter well in the Lee powder measure. As does 231 and bullseye, and just about any of the faster burning powders. I never considered the 357 case to be position sensitive with powder or prone to shape charging like the larger bore pistol cartridges are with light loads of fast burning powders.
    Unique doesn't meter well in most powder measures and I've found it to be static prone in my reloading room. Other people may not have that problem.
    I will say this though, my lee pro autodisc powder measure on my pro1000 will throw more consistent loads of Unique then my Hornady or RCBS uni-flow measures will.
    Go figure. (Again, maybe static induced)
    Don't be afraid to try Unique, It's been around since like 1899 and is tried and true for accuracy. Unique is usually a Love-Hate relationship with not much in between.
    Just my opinion.

    Any powder that will work for both 9mm and 357Mag will not give that punch in 357Mag you are looking for. You need a slower powder like 2400 for that and it doesn’t work in 9mm. You simply can’t cut corners by using one powder and still get maximum performance from both.

    I've been shooting .357 LSWC cutters and jacketed 9mm over Unique with no problems.

    If you're loading 9mm to full power and want to load .357 Magnum to about 100 to 150 FPS of full velocity, the best powder you're likely to find for it is AA#7. ;)

    AA#7..full house 9mm (especially with heavier bullets) and not quite full house 357. In my last keg of powder I had worked up loads that were REAL close to H110 / W296 velocity.

    Next up is Longshot.

    There are many medium burn rate powders that will work fairly well in both the 9mm and .357 Magnum.

    They include:
    Power Pistol
    AA#5 or AA#7
    HS-6
    Longshot
    And probably a few more but those are the powders I know first hand work for both... Note, faster powders like W231/HP-38 and a few others can also be used for both but will not deliver real magnum performance in the .357 Magnum. The listed powders will at least deliver lower end real magnum power while slower powders like 2400, AA#9, W296/H110 and the like will produce top end power.

    For the life of my I can not figure out why so many reloaders want to use only 1 powder for none similar cartridges. You really save nothing using 1 powder that really isn't optimum for each and you cheat yourself of one of the main reasons for reloading, better performance that factory ammo. That said, if I really had to pick only one powder for those two calibers it would be HS-6.

    Just get Bullseye for all your pistol loads. End of story.

    I use Bullseye for 9MM, 357, and 45 ACP.

    Bullseye, really? That is just about the last powder I would use in a .357 Magnum. that powder is way too fast for good results. Alliant doesn't even list Bullseye for the .357 Magnum other than with lead bullets. If you would have said Unique, sure, but Bullseye?

    I recommend Alliant's BlueDot powder for hot 9mm and hot .357 mag. For 9mm it burns clean enough for me and has a nice flash with top speeds. In .357 mag it provides magnum power for bullets ABOVE 125 grains ONLY!

    I really like HS-6 in 9mm, and it'll provide some of the higher velocities for .357 from the non magnum powders.

    Paying double what it costs me to load 9mm is cheap? I load 124 jhp ammo in 9mm for $12.50 per 100 rounds. It takes me 3 minutes to load 100 rounds.....well 4 minutes if you include loading up the primer tube with primers and throwing bullets in the bullet feeder.

    You could use less expensive bullets and go cheaper yet. Savings is usually 50% or more for metallic centerfire ammo. I can't buy components for 12 ga target loads as cheap as I can buy the finished winchester ammo, otherwise I would load for shotgun too.

    I love hp-38/win231 for small pistols and for light magnum pistol loads. I use trail boss for light 460 Mag pistol loads. It will work for any pistol or rifle, but may not work the action on some semi autos. h-110/win 296 is common for magnum full power loads. It is no big deal to use multiple powders. I try to stick to only a handful to make it easier though. It can be fun to work up new loads and run them on a chrono, but I also like to stick with a load after it is proven.

    My pet 9mm load is 4.2 grains of win 231 and a MG 124 JHP seated to 1.125" at a speed of 970fps.

    I am going to give moly coated lead bullets another try in my 9mm competition gun though. MG bullets are up to $91 per K and I can get bear creek moly for $57 per K. It is hard to spend that extra money.

    I have a similar load and I also like W231/HP-38 for most of my handgun loading in spite of what I posted above because I don't like it for magnum calibers. I usually charge 4.0gr W231 under a 124/125gr LRN bullet and 4.4gr W231 under a 124gr FMJ bullet. Both are great 9mm loads which are clean and accurate for me...

    Are you really getting 970 fps from a 4.2gr charge of W231 under a 124gr JHP bullet? I haven't sent mine over a chrono yet but I didn't think the velocity would be that high. How long is the barrel on the pistol that delivered 970 fps?

    Great Info Guys...

    I had no Clue that it was such a difference in Powder for a 9mm and .357.... Since I will start with 1lb of powder most likely, I will try 2 different for each then.... and Possibly try a AA#7 for both and see what the results are...

    Heading out today to try some new loads for .357 (factory) and see how i like them over .38special rounds...

    Also gunna $$$ out new gear for .357 loading... see what it actualy costs localy 1st...


    thanks again guys

    Stavman be sure you don't push your model 19 too hard. Take this from someone who has cracked a forcing cone on mine. Search "cracked forcing cone model 19" for more info. Also stay with the 158 grain bullets.

    I stick with mid-range power pistol and 2400 loads for mine and usually use lead 158 grainers. Don't use the 125's at high velocity in your 19.

    Another vote for AA #7, it will match factory 125/1450fps with a 4" barrel. It's also a very good powder for the 38 Super and 10mm.

    Nice thing about loading for 357 is you can load light and have the same as 38spl and by using 357 brass you don't have the carbon ring build up in the cylinder. just add 10% to your 38 powder loads to account for the larger case volume.

    For full house .357 magnum loads H110 / 296 and a jacketed HP will top the list. Just don't try to reduce this powder to less than minimum published data or it will perform very poorly, possibly even fail to ignite or produce squibs.

    And for the 9mm, Longshot behind a jacketed bullet will produce some full power loads. I like Longshot because it doesn't get spikey when working up. It also fills the case up nicely, thus making it impossible to severely over charge a case, or double charge one. This powder is also very good in a 38 spcl. and .40 S&W load.

    HS-6 is another good powder for 9mm, 38 spcl., and .40 S&W. It is also a slower burning powder, much like Longshot in this respect.

    They used to (thru 2004) list it with every bullet, and the performance was pretty good. They took it out when they revamped their load book to push Speer bullets.

    I also use Bullseye for 9mm +P loads and like it. It doesn't get peaky at the top end like many other powders.

    All that said, Power Pistol or AA#7 might be a better choice.
