    I run an XD 40 Service model (4" barrel) with a 9mm barsto conversion barrel that is hand fit to my gun. The gun has 30k+ rounds through it and is on the original recoil spring. It does have a bunch of other upgrades for competition. The barsto barrel has probably around 10k+ rounds through it. I don't really keep track of rounds, but I go through a lot of bullets. 99% of the ammo run through my gun is hand loaded by me, and is low power.

    This load is actually pretty weak. It is a bit too light to meet minimum power factor for some sanctioned matches. This load also will just cycle my gun when I shoot weak hand only. Single strong hand and two hand holds run just fine.

    This is from my CED M2 at 6-10' away on a mild spring day in SoCal.

    Chris XD 9mm 124 JHP 4.2 Win 231
    1) 961.1 -7.6
    2) 989.3 20.6
    3) 963 -5.7
    4) 961.2 -7.5
    5) 969.1 0.4

    High: 989.3
    Low: 961.1
    E.S.: 28.2
    Ave.: 968.7
    S.D.: 11.9
    95%: 16.5


    I bought some frangible bullets from midway. A 90 grain CTF Remington bullet over 5.0 grains of win 231 seated to 1.130" comes out just slightly below 1200 fps. This load runs just as well as the MG 124 JHP load, but I only paid $50 per K for the bullets when they were on sale. MG's are now $91 per K when bought by the case.

    H110/W296 or 2400 for the 357 or don't bother. I'm partial to H110 but I just started working up some loads with 2400. I'm of the opinion that if you are shooting a magnum firearm then you should load it to full power. I have other firearms for powder puff loads :)

    If I was loading 9mm and .357mag and only wanted to use (1) powder for both, I would make the choice in the following order:

    (1) Bluedot

    (2) HS-6

    (3) Power Pistol

    (4) W-231

    (5) Titegroup

    (6) Unique

    Any of these powders will load successfully with standard primers for simplicity. I don't have any metering problems with the listed powders either. YMMV.

    Any one powder will be a compromise. While Unique or Universal Clays can do a decent job in 9mm they will not give you the 357 performance that other choices will.

    I suggest you read up about reloading both and buy two powders - it doesn't cost that much

    In this case there are powders that can give top 9mm performance and still give 90+% 357 across the board. They may still be a compromise but we are talking about working between the 45 yard lines.

    BTW 4895 lots of flash is not a feature...rather a detraction for the use of Blue Dot. Modern defensive / carry ammo is LOW FLASH for the more common time / situation you would use it in.... low light conditions. Besides, Blue Dot has been determined by the manufacturer to be questionable (read Liability issues) with 125 gr. 357 loads; they have issued specific admonishments against this use. No doubt due to it's 'peaky' tendencies in certain loadings.

    AA#7 is my choice for factory level 9mm and upper mid range 357. It won't quite achieve full magnum velocities vs. H110 but it is good enough for most 357 needs.

    Didn't know this was for carry/defense ammo. I thought we were talking about range fodder. Bluedot does have a big bang/flash thing going on. I like it, and I purchase my carry ammo over the counter.

    The S&W 19 the OP is using isn't suitable for heavy loaded 125 grain bullets. I suggest 158 grain bullets to keep wear to a minimum. It isn't a Ruger after all and will break quite easily if pushed too hard with light bullets.

    That is why I suggested Blue Dot. It will give near peak velocities in both calibers. I use it with 125 grain FMJ in 9mm and also in 158 grain SJHP .357 mag with no problems.

    I have never had a problem with it in 125 grain bullet loadings, but do concur that Alliant has issued a statement warning reloaders not to use the published load data of BlueDot with 125 grain pills in .357 magnum nor any loading in .41 magnum IIRC.

    Magnum Shooter hit the nail on the head in Post # 4.

    If it works in 9mm it won't give top velocity in .357 Magnum.
    And powders that work well in .357, won't have data available in 9mm because the chamber pressure would be too great.

    The second part is incorrect; actually the opposite is true. You can't stuff enough of the real slow powders into a 9mm case to get the pressure up to the proper levels for it to work right. With many loads of Blue Dot or AA#7 you are running into compressed loads in a 9mm and these powders are faster than the powders that give "top" performance in a 357.

    And considering the OP is shooting an M19, AA#7 will give him all the velocity he's likely to want to load to for it. For full power loads with 124 and 147 gr. bullets in 9mm, it's one of the best powders available. ;)

    Unique will work with both fine. With the .357 you can still get some pretty good velocity. Unless you need very max .357 power you can use mid power loads with the Unique which it excels at. It's easier on gun and shooter.

    i think you would be better off just to buy two types of powder
    i like Bullseye for 9mm and H110 for magnum loads in the 357 mag
    just my 2 cents

    Another fan of AA-7 for full power jacketed 9mm loads, and mid-level 357 mag jacketed loads. Both with Fed small pistol mag primers.

    Unique comes close, but is harder to full power in 9mm, and does not quite equal the velocity in 357.

    That said, if I really had to pick only one powder for those two calibers it would be

    :)Arch is spot on again for his choice.

    For med. loads in 9MM, .357, and .45cp. HS-6 is hard to beat..Bill.
