    I am thinking of loading for my 4 5/8" Ruger blackhawk in .357magnum, what is the classic powder/primer/jacketedbullet for .357? I only currently load for half a dozen rifle cartridges and wanting to load a factory level 125 to 158 grain load for paper punching with a handgun.

    For a classic full power .357 load I would use 2400 powder any good 158gr. jacketed bullet and a sp primer. If your just punching paper and want a lighter load substitute Unique powder for 2400.

    I'd recommend 2400 as well. 14.8gr of it will throw a 158gr Missouri hardcast SWC over 1500 fps (6" GP100).

    No classic 357 load uses a jacket. Use 2400 and a cast bullet. Use the max load (after adhering to proper load development procedures). You'll get close to 1300fps in that gun with that load and you'll make Bill Jordan and Elmer proud.

    I have to agree with Whiskey because that is the Classic 357 load. SJ 40

    This, some data have you use a magnum primer also.

    For a true "classic" load the bullet would be a JSP.

    An "antique" load would have used a heavy Keith style cast bullet.

    I agree.

    A "classic" load for a .357 is a hard cast lead bullet and either Unique or 2400 powder.

    Antique? :miff:


    158 grain Keith lswc and 2400. If a handgun load gets better than this, I haven't found it yet. Maybe the most accurate load from any of my handguns in any caliber, and it will go through 2 feet of darn near any flesh and bone you care to put in front of it.


    Keep in mind if you're going to use Unique - just because it's "mid-range" in performance doesn't mean it's mid-range in pressure. Easy to over-do it with that fast of a powder in a magnum cartridge.

    Go slow, work up, be safe and have fun.

    Well, the 357mag started w/ a swaged lead bullet @ high enough vel to lead badly. A hard cast 158grLSWC @ 1350-1450fps is about as good as it gets in bbls under 6". 2400 would be the "classic" powder of choice, but H110/W296 work really well for max effort loads. A 170grLSWC is even better.:supergrin:
