Powder Recommendations for 38 Special +P 158 LSWCHP?

    I am looking especially for first hand experience others have had with this combination. I am considering loading 38 Special +P with 158 lead semi-wadcutter hollow points, trying to mimmick or duplicate the FBI load using a Speer 158 LSWCHP.

    I have tried Unique and Bullseye and they were way too dirty. I also have tried Trail Boss, but it was too weak to get it into 800+fps that I want (from a 4" tube.) I do like Trail Boss quite a bit, it seems very cool and clean burning. (Is this partially because of the fact that it is a single based powder?)

    I am considering trying SR4756, a single based flake powder that, in my research, appears "fluffy." (I don't own any yet.) I am reluctant to try any more Alliant double based flake powders, such as Power Pistol, due to my experiences. These will be fired in a .357 Magnum GP100, for what it's worth.

    Any advice?

    checkout www.ramshot.com and look at the data for Silhouette and True Blue. Both will meter exceptionally and Silhouette is treated for flash. True Blue is a very fine ball powder that meters as well as any powder can. ;)

    My "FBI" load uses Speer 158 grain LSWC-HP and max Alliant Power Pistol data. I'm getting 927 fps from a 3" Model 60, with nice accuracy, clean, and excellent bullet expansion. Even using circa 1994 Hodgdon max +P data (7.3 grains) for HS-6 and a 158 grain lead bullet, it falls 60 fps short of the PP load, and nowhere near as clean... Just another load in my experience where Power Pistol excels, and the more I use it, the more I like it for a lot of pistol calibers.

    How can you tell?

    If you are shooting cast lead bullets, the dirty part is caused by the bullet lube blowing & burning off, and sticking to everything that gets in it's way.

    Different powder isn't going to fix that.

    Before switching to plated bullets, I loaded 158gr LRN over 3.5gr Clay's. From my 4" 686, they chrono'd at 816 - 820 fps, IIRC. I know others who use Solo1000. Both powders are about as clean as you'll get shooting lead.

    Because I was there?

    They were not cast, they were Speer LSWCHP as I mentioned in my OP.

    And different powder did fix that.

    The 2 +P loads I use is 4.5 to 4.7grs of W231 or 5.0 to 5.2grs of Unique with the Speer 158gr LSWCHP with Winchester primers in a Winchester case. Both loads do around 900 fps + chrono'd average out of various 4" revolvers.

    3.8grs of Tightgroup averaged 877 fps from my S&W 67 4".

    I got outstanding success using HS-6 in my FBI replica loads. That powder will deliver all the velocity you are looking for while keeping the pressures lower than most other powders in it's burn rate range. HS-6 doesn't create excessive flash like Power Pistol does either. Accuracy is very good too in all my revolvers... My data is in the post on the second link listed above to the S&W site.

    I use ww231/HP38 for my FBI duplicate load. however I have used Unique I always find it amusing when somebody talks about how dirty Unique is Sure it may leave a little more soot on the gun than the so called clean powders do, but it wipes right off. I mean if you find a powder that burns pretty clean are you gonna leave the gun just a little dirty?

    I loaded a lot of .38s with 158 gr cast SWC or RN and 4.6 gr W231.
    Velocity ran from 820 to a blazing 942 fps depending on gun (all 4" though), bullet brand, powder lot, and temperature.

    I now settle for 4.3 which goes 800 fps +/-.

    I use 4gr of Red Dot with 158gr SWC. Been using that load since the late 60s.

    Here's some data from last summer with those Speer bullets, six inch barrel:

    A#5 6.3 WSP primers 7/3/11

    lo 909
    hi 944
    av 929
    sd 12.7

    True Blue 5.6 WSP primers 8/13/11

    lo 822
    hi 881
    av 857
    sd 20.0

    The A#5 load is from the Speer manual which shows 6.2-6.6.
    The True Blue load is the max from the Ramshot manual, but they don't show any +P loads for lead bullets.

    I'm happy with the A#5 load so I stopped experimenting with this. If I needed to use another powder I'd try any of the load data recommended in the Speer manual. It's the only manual I have that lets me expect to see something close to the published velocities.

    AA #5 will do what you want.

    I hate Unique with a passion even though it was my powder of choice for 20 years. I would try either Universal or Power Pistol, they give excellent velocity and are cleaner burning.

    About 5 years ago I had enough of Unique, powder measures seem to have trouble with it. I tried the 2 powders above and was very happy with both. I'm still trying to decide between the 2 of them. Universal is pretty much like Unique. Power Pistol gives some really good velocity in cartridges like .38 Spl, .44 Spl and .45 acp. I use it exclusively in .38 Spl and 9mm at present.

    Power pistol, combined with Rim Rock's 158 LSWCHPGC might just be my ticket!

    Looks like it would be a good powder for 135 GDHP in mild .357 as well.

    Power Pistol will probably do what you want EXCEPT you will have to deal with the excessive flash and the additional report generated by Power Pistol. Since there are several other powders like HS-6, Longshot, AA#5, True Blue and a few other that will do just as well I refuse to deal with the shortcomings of Power Pistol.

    As for a 135gr mild .357 Magnum load, I have made good 135gr Speer SB replica loads. I found Power Pistol to work very well replicating the Speer magnum load. Using a 135gr GDHP ot 140gr XTP bullet a charge of 8.8gr Power Pistol delivered right around 995 fps from a 2" barrel. I stopped using it because the flash was unacceptable especially in low light conditions. I was able to get the same results using HS-6 without the excessive flash. To replicate the 135gr Speer SB .38 Special +P ammo I use AA#5.

    I load them with 4.5 grains of either American Select or Rex-3 (Rex-3 is a defunct powder equivalent to Universal Clays, but I haven't actually tried Universal yet) This should give 950+ fps from a 4" revolver.

    You can go a little faster than that with enough Unique or Herco or AA#5 or True Blue. (anything slower will be too flashy)

    Sounds real good, and can EASILY do the 800+ fps what you originally spec'd it to do from a 4" revolver... I'd fully expect very close to 1000 fps at max Alliant data in many 4" revolvers Nice choice for the 135's too.
