    10 grains of Unique should get you around 1000 f.p.s.

    A disadvantage with Unique or other fast powders is the possibility of double charging. My range has a S&W 57 on display that has only 1/2 of its cylinder. The shooter didn't get hurt, but the gun is ruined.

    Double Charging with Unique is not a problem if you inspect the cases before seating the bullets . I use a reloading block and shine a flashlight down the cases before seating the bullets . A double charge would be " Very " evident . My favorite load load in 44 magnum , using Unique powder is 9.3 grs with the actual Keith bullet , " H&G 503 " . My experience with the Lyman 429421 is that it's close , but not exact like the H&G mold . Regards, Paul

    I am a very devoted fan of HS6 powder for the 44.

    From the Hodgdon’s #26 manual: 250 gr of lead, 10.0 gr to 12.0 gr HS 6 powder. I use a magnum primer and get pressures in the 24,000 psi (I stopped at 11.8 gr just because it shoots so well)

    My 4” Mountain Gun gives me 1066 FPS with a mere 7 FPS Standard Deviation and my 7.5” RH runs 1176 FPS with 15 FPS SD. (RCBS 250K)

    It is EASY on the paws and the powder runs like butter on a hot skillet through a measure.

    I run Unique and 2400, both great powders. I like Unique as Skeeter Skelton used it (8.5 gr in magnum cases) but prefer HS6 to go ver 1000 FPS in a 4” revolver. I run 2400 from 17.5 gr and a magnum primer, from around 18.5 I step down to standard primers. But primarily I run 2400 at 20.0 to 21 gr. (std primers)

    But at that upper medium field load range HS 6 out performs both of these powders. You can find HS 6 loaded into the mid 30k range but that defeats the whole point of keeping lead in the mid 20k range. Obutrate it enough, but not exceed its yield strength.

    My full throttle gets Mag primers and H110 and they will run the lead into that higher pressure but I fire so few of these that I suppose excessive leading is avoided.

    Quit fretting about climate change. Itís how much stronger gravity is getting every day that is bothering me!

    Three44s,

    Why do you use a magnum primer with HS6? I assumed it was an easy to light powder.

Myths, especially when some writer states them in a magazine, are hard to dispel, even with facts.
    As a lurker, I've referred to your postings on .44 Magnum/2400 pressures a few times. I like it when we can cut through all the internet-isms and get some real data.

    I worked up to the Keith load(using RCBS 250-K and CCI standard primers) with no problem.

    That level of power isn't technically "necessary" for most jobs I'll ever need to do with it, but I like my Magnums to be Magnums, from time to time.

    Sorry for not checking in sooner!

    HS6 is picked on for being dirty and as a spherical powder that is not fast, I went with magnum primers. Besides inside flash hole deburring, I also trim case lengths to a standard length appropriate to my batch of cases and then follow up with a good roll crimp.

    All taken together, a standard deviation of just 7 FPS and accuracy to match, I do not see a reason to change to standard primers?

    I have done a small batch of standard primers in a 41 Mag with all my other load prep and it was not nearly as clean, so that was the end of that.

    Best regards and stay safe!

    I recently checked an old loading manual, Speer #11, and ALL the 44 Mag loads with HS6 are designated with magnum primers. So Speer agrees with you. I am waiting for my Model 29 cylinder to come back from DougGuy. When it does, I will be trying 2 powders- Universal and HS6. Thanks for the the info.
