    Alliant Powder lists 14.9 grains of powder for a 158 grain jacketed bullet, for .357 mag.
    This really fills the case, almost to a compressed charge.
    Is this correct?
    Loaded one with 11 grains, wasn't too bad. But i'm concerned with a pretty close to compressed charge. Comments appreciated.Thanks!

    That's what my Lyman reloading manual #49 list as well for jacketed bullet in revolvers in the 158 gr. range. I've never really found the need to push it to the Max. load with J bullets but I've come close,I load for accuracy and I've found that 14.5 grs. does just fine with both 158 gr. jacketed and my cast lead bullets.

    Compressed loads are not a problem,2400 is sorta bulky put your finger tip over the case mouth and give it a few taps and it will settle some,the 14.9 gr. load is a Max. load not something you necessarily want to start outwith and it's not listed as a compressed load in the 357 either.

    14.5 is my go to load for 2400 in .357 mag with 158 gr XTPs.

    That is a relatively slow powder for handguns and should just about completely fill the case.

    There are lots of different powders out there, we choose the one we want based on what we want the bullet to do. I'm looking for a powder that will give me more loads per pound, thus, saving me money. I choose Acurate Powder for that very reason. They list #5, 9.7grs, for 1256fps, as a max load. And 8.6grs for 1100fps., as a starting load.

    Myles, I use titegroup for the very same reasons. Hodgdons data site lists 5.4 @ 1135 fps with a 158 XTP as a starting charge and 6.1 @ 1229 as MAX. Very economical powder and very clean burning. Its every bit as clean, if not cleaner, as accurate #2 is.

    I've been shooting the following in my Henry rifle (22" barrel):

    Hornady 158 grain FP/XTP's, WSPM primer, 2400 @ 15.2 grains
    The gun shoots them well, no problems at 1654 fps.

    A little better load (for me) was: Hornady 158 grain FP/XTP's, WSPM primer, Winchester 296 @ 16.7 grains. I'm showing 1700 fps. The accuracy with this load is a little better and I like the sound of the load.

    Think I like JLA's input... Yer probly gonna blow most of yer 2400 out the barrel of a pistol when loading max volumes. My 71/2" 44 is that way. Give me a bit more speed in the burn!

    Thanks all, at least I'm not losing my handloading mind.
    Titegroup is my "go to" powder and i just had a pound of 2400 on the shelf.
    After using Titegroup for the .357, the 2400 charge seemed extreme.
    Better to be safe and ask than sorry.

    dbach-what Henry rifle are you firing those loads out of? I know the magnum has a 20" barrel you said 22".

    In the days ahead I will be loading some 158 cast and some Hornady 180 gn, HPXTP... with 2400 powder/ I let ya'll know how it goes.

    Mine is a Henry H006M, .357/.38 I was mistaken, it is a 20" barrel.
