    I didn't, I sent a couple of emails and never got a response and got busy with other things. My LabRadar seems to jive very closely with the results crockett got with his on similar loads (UW +P XP).

    Yes, similar to trying to ignite wet newspapers... :)

    Once you get it going though, well THAT'S AFIRE!

    Just a warning for those that may not know, back off considerably when switching to "mag" primers especially when near top end loads!
    From my experience they drastically increase pressures and normally don't add enough velocity to worry about except in large case with hard to ignite powder like 296/H110 etc.

    I had a chance to finish testing the most recent round with WSF and W572. I am loading all of these on my Dillon powder drop on my 550B.

    Last time I forgot my OEM barrel at home, so all of the forgoing records are with my stock length Alpha Wolf barrel.

    I focused this reshoot with the OEM barrel, mainly watching for smiles. I really prefer using my OEM barrel first on any ladder as it starts smiling cases when getting to max pressures, kind of a canary in the coal mine. The AW barrel has never smiled a case, so I am playing a little blind mans bluff with pressures when testing new loads with the AW barrel alone.

    I started at 5.0gr of WSF with the OEM barrel. When I did the W572, I went another couple rungs up the ladder to 5.4gr and 5.6gr and recorded both the AW and OEM barrel velocities. As I expected, as I got to 5.4gr of WSF and 5.4gr of W572, I started to see a few smiles, but none as pronounced as the Underwood +P loads impart in my OEM barrel (consistently smiled).

    W572 - 5.0 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1035 FPS, SD 32, ES 85 - G42 OEM Brl
    W572 - 5.2 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1085 FPS, SD 38, ES 83 - G42 OEM Brl
    W572 - 5.4 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1097 FPS, SD 29, ES 72 - G42 OEM Brl
    W572 - 5.4 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1159 FPS, SD 16, ES 45 - G42 AW Brl
    W572 - 5.6 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1151 FPS, SD 27, ES 69 - G42 OEM Brl
    W572 - 5.6 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1174 FPS, SD 15, ES 39 - G42 AW Brl
    WSF - 5.0 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1092 FPS, SD 29, ES 70 - G42 OEM Brl
    WSF - 5.2 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1123 FPS, SD 12, ES 27 - G42 OEM Brl
    WSF - 5.4 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1133 FPS, SD 18, ES 37 - G42 OEM Brl

    I am pretty sure both WSF and W571 will get me equal results to the Underwood +P XTP loads, when I start testing XTP's. It looks like I am going to settle on CFE Pistol, BE86, W571 and WSF for my final rounds using XTP bullets.

    After I am done with my workups and have selected finalist for my UW +P simulator loads for practice, I will circle back and do workups for the Lehigh XP and XD bullets.

    Phew.

    *******. Warning, the loads in this thread are my workups in my gun. Many are well over book loads and should not be used as a load guide. It is for your amusement and gratification only! Do not use these loads in you gun. You must work up your own loads and you must only do that if you have the required experience. *********************

    I may do that, but lately things have gotten more busy than less. The good news is the puppy is well and other than everything being chewed, I am getting almost a full night's sleep.

    We just bought some land and after it is redrawn on the map, we will be building what is likely going to be our last house. I had to buy about 3x as much land as I wanted, to be able to end up with the plot I wanted. I will sell off the remaining three parcels after I get it redivided the way I want. Going to build a modern farmhouse, with everything exactly the way we want it (and for how we live now) and in a place exactly where we decided we wanted to be.

    The bad news is it will be a big time sink for the next year +/-. I will get the workups done and a final load decided upon, but I suspect gel testing (or any terminal ballistics comparisons) will have to be for someone else to get done.

    Some fun.

    If you decide to use any of the above load information, you got to make it your load, not mine. :) That is, you need to work it up in your gun and be satisfied it is safe in your gun, based on your experience and judgement.

    I am pretty sure once I get to loading the XTP's with the above four powder candidates, I can get to similar velocities that UW delivers with their +P loads. I think the smiling (while likely not as consistent as UW delivers) will be very similar in the OEM barrel. I expect the XTP's will seal much like the Gold Dots did, which will get me over the hump with loads that are already published above. I guess this is my version of a copper crusher test. ;)

    WW, when you get done with the 380, what
    caliber are you going to do next?

    Do you have any 357 mags?

    I do have a few 357's, but I suspect there probably isn't anything I can add to the last 75 years of the cartridge that was first loaded by the likes of EK. :)

    I think with the 380, there was fertile ground for running pressures up closer to 9mm (modern guns, etc), with 357M, kind of like 10mm, there are probably not a lot of secrets to be discovered.

    I still have quite a bit of work cleaning up and publishing the foregoing results in one concise thread, sans all the personal stuff, including getting those Lehigh loads done.

    What kind of 357 you got.

    What we have now is better than
    anything they had before around 85.

    Thanks to JD Jones and Veral Smith,
    they kinda re invented the mags, we
    also have many new powders.

    Now, I have a couple of Rugers, one Blackhawk and one GP 100, a couple of Smiths, a Model 27 target gun and an R8. I traded my favorite 357 of all time, a Model 19. Probably the worst move I ever made with a gun. I was like JM with that gun. :(

    I have a 50 cal ammo box full of my favorite 357 loads. One day I will get back into those, one day. :)

    I think what happens is as you get older, everything takes more time. Kind of ironic because as you get older, you have less and less time... ;)
