    I finally got around to making a load for my GP100. After some research and not finding much to go on for Titegroup I started my load at 6.5GR. My first batch were made using 158gr xtreme plated RNFP, S&B SPP, and an OAL of 1.575. I also used a single stage press to make these 6. I made chrono'ed at 1024, 1056, 175, 1108, 1057, and 1086. The extreme spread was 84 with a standard deviation of 28.

    I then set up the Dillon 450 for 357 to see if it made a difference. This time I used 6.5 gr Titegroup, 158 gr Semi Jacketed Hornady XTP #3575 bullets from sometime in the 80's. I loaded them to an OAL of 1.590. The chrono came back at 1131, 1122, 1118, 1109, 1107, and 1091. The extreme spread was 40 and standard deviation was 13.

    Since I will run out of the old school Hornady bullets before the xtremes I have I decided to try again on the 450 the 158 gr plated. I used the setup I had for the previous OAL, but ended up with 6 rounds OAL of 1.586, 1.587, 1.588, 1.589, 1.588, 1.587. The chrono came back with 1054, 1077, 1111, 1073, 1060, and 1068. The extreme spread was 57 with a standard deviation of 20.


    I shot each round by itself and checked the brass for any splits, or pressure signs. I did not see any, and the cases were pretty clean. Forgot to mention the brass I used was NOS Midway head stamped brass.


    From my observations I was able to load a tighter round with the 450 than on a single press. I also think the velocities I got on the Chorno are well within range for 357. I did notice though that when I started to load on the progressive my OAL slowly went from 1.586 to 1.589 and then started back down to 1.587 as the positions became empty.



    Feel free to critique or make suggestions to better my 2nd and 3rd loadings.

    The posted chrono velocities seem reasonably good. I like TiteGroup for some applications, but not for magnum pistol. I used the old IMR 4227 for a while, but have stuck with AA#9 ever since I tried it. It takes a lot of powder, and is a little dirty, but the performance is great, very stable from the lightest load to the max loads. WW296 worked ok, but got really inconsistent if you tried backing the loads down too far. Blue Dot was inconsistent through my measure, but shot pretty good.

    Small charges of slow burning powder and guns are generally not a good thing.
    Pressures go way up and guns come apart.
    17 squirrel has a Super Blackhawk in 44 he blew up long ago with a short charge of 2400 from not pushing the powder measure all the way in on his Dillon 450.

    I used Titegroup in my revolver for just a short time, but some guys on here said it could start doing a flame cut on the frame so I use 2400 or W296
    .

    It's a hot burning powder, and will flame cut faster than other powders. I'm not sure how much of an issue it would be in a GP100, but I steer clear of it for k-frames and Colts.

    I've shot maybe a good 1000-1500 38's made with titegroup with no issues so far. I think I use 4.2 or 4.3 gr in those under a 158gr xtreme plated.

    .38spl cast bullets loading is a good application for TiteGroup. At that low of pressure, I have no worries about flame cutting, even on my smith.

    I have used Unique for .357. I think it was still a Hercules powder at the time. It works pretty good but my powder throw did not like the shape of the powder flakes. Once I started loading enough to buy a progressive loading press, I only stopped using it because of handling, there was no performance problem.

    I just don't understand why people insist on using Titegroup in applications it simply isn't well-suited for, like in a magnum case. It is a false economy to use less powder, creating a situation where a double-charge is possible. You also give up considerable velocity (around 250fps, in this example) by choosing Titegroup instead of 2400, Li'l Gun or H110.

    You can drive in framing nails with a tack hammer...but why would you? Use the right tool for the job.

    Wanted to try Unique. Heard good things about it. Could not get my hands on 2400. Loaded .357 158gr. jsp with 7.6 grs. of unique. Thats splitting the min. and max according to lymans manual. In a gp100 I don't think there will be any problems with pressure. That revolver is built like a tank.

    I don't like to have to empty my hoppers to load a new powder. The FPS I'm getting from my OP is good for me. I may try to bring the SD down under 10 but will take to the range first.
