    Using Lyman as a source. This data is for 158gr Jacketed hollow point and Unique powder. This is the closest thing I can find for what you are wanting. I wouldn't be afraid to use this data.

    38Spl:
    Start- 4.7gr , Vel. 645, Pressure C.U.P. 14,400

    Max - 5.0gr , Vel. 710 , Pressure C.U.P. 16,600

    .357Mag

    Start - 6.4gr , Vel. 887 , Pressure C.U.P. 18,900

    Max - 8.3gr , Vel. 1185 , Pressure C.U.P. 38,300


    Hope this helps!

    ARGH!! You want Bullseye! [B)][:(]

    I'll dig that up for you.

    EDIT: No luck for Bullseye. My manual doesn't have it listed.

    Sorry

    From my Speer book...

    158gr Jacketed SP, Bullseye powder.

    38 spl
    starting load 3.8gr for 801 fps
    Max load 4.2gr for 888pfs

    38 spl +P
    start - 4.2gr for 813fps
    Max - 4.9gr for 850fps

    The velocity figures don't make much sense, but that's what the book shows.

    357mag

    Start 6.6gr for 1028fps
    Max 7.1gr good for 1123fps

    The problem with Bullseye is that it's burn-rate is so fast that it isn't really safe to use with the heavy, jacketed bullets. Clays is the fastest powder recommended for that bullet. The minimum load using Clays is 2.6 grains. Therefore you would have to go down to 1-1.5 grains of powder as your starting load with Bullseye. That really isn't that practical, along with the fact that the whole powder charge would probably wind up below the flash hole when horizontal which causes problems too.

    Have you tried the Alliant Website?

    They have data for a 158gr JSP, should carry over to your bullet...

    http://www.alliantpowder.com/reloaders/RecipeList.aspx?gauge=&gtypeid=1&title=Pistols and Revolvers

    scroll down to the 357 series of loads...

    I also had trouble with Bullseye for heavier bullets in 38/357.
    Using it to load 44 SPL was just worse.
    I never had any failures or indications of pressure problems, they just didn't group well.

    At the time (30yrs back), a fellow loader suggested using some 'filler' to keep the powder in the back of the case, not lying along the inner volume. I believe the filler material was 'kapok' or similar at the time. It was fine as an experience, but it was just not worth it.

    HOWEVER...IF I AM IN THE SHTF TIMES, I do know that I CAN load the fast powder in the larger volume cases and get pretty good results using a filler. I have a related question on a 'modern filler', but I'll start another topic.

    ENJOY !

    i talked to the guy at alliant the other day, and he suggested to go to a lighter bullet for the 38 loads. he said he liked the 125 in maybe a jsp or jhp. so i ordered some yesterday. the 158 grn. is good for the .357 load. ill let ya know how it turned out.

    We have been using lead 158 bullets with 2.8g of Bullseye in 38 spl for 30+ years and got the load from the South Dakota state police. They shoot great and are nice light target loads.

    Source- Speer Manual #10.

    38 Special- 158 Gr JSP, Bullseye 4.3 gr 813 FPS. 4.9 gr is a +P load at 850 fps.

    357 158 gr JSP, 6.6 gr Bullseye, 1026 fps, MAX 7.1 gr, 1123 fps

    Based on a Ruger Security 6, using CCI 500- 550 primers.

    I load heavy JSP 357 rounds for hunting with a 12 inch revolver- want penetration. For 2 legged critters, the 125 is a better pill. Good luck w/ your loads.
