    I thought I had shot the 65gr XD'on camera!
    Fast Forward to the 5:27 mark in the video.

    Thanks for the test. Gotta love the Lehigh bullets. I load the 90 gr XD for my 42.

    Can you take a pic of your loaded 90gr XD, and what brass manufacturer are you using. Thanks Tim.

    I got a chance to shoot some more tests today. I will post the results hopefully this evening when I get a little time, but the surprise dark horse turned out to be WSF. I had determined in previous testing that Unique seemed to have the exact burn characteristics we wanted for a max effort 380 load matching UW +P velocities and apparent pressure signs. The problem with Unique was its load density, basically running out of room in the case before we got what we needed.

    It dawned on my that WSF likely would match Unique in rate, but have much better load density potential. It turned out my guess was right. I got very close to UW +P levels and actually had less in the way of pressure signs. I will post all my results as I also did W572 and AA#5, but WSF and BE86 seem to be the two with the most potential as finalists.

    I had a chance to get another round done with WSF, AA #5 and W572. I am loading all of these on my Dillon powder drop on my 550B.

    I forgot my OEM barrel at home, so all of the following is with my stock length Alpha Wolf barrel. It has been 100% since I polished the feed ramp, so it is my carry barrel. I will go back and test these same loads with the OEM barrel and suspect like in the past, they will be a little slower (looser chamber).

    I ran out of Gold Dots at 4.8gr,so from 5.0gr on, I only had PD 95gr FMJ/FP, which run a little slower than the softer Gold Dots (better sealing I suspect).

    The WSF seems to have a lot more headroom left yet, but I won't know for sure until I get the OEM barrel in the loop and start checking for smiles. The AW barrel just doesn't smile cases, at least at the pressures we are running. Primers looked pretty good at max today, although at 5.4gr of WSF I was starting to see some mild extractor rash.

    WSF - 4.6 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1057 FPS, SD 34, ES 87 - G42 AW Brl
    WSF - 4.6 gr, 90gr Gold Dot, .950" OAL, CCI SP, SA 1096 FPS, SD 15, ES 40 - G42 AW Brl
    WSF - 4.8 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1068 FPS, SD 45, ES 43 - G42 AW Brl
    WSF - 4.8 gr, 90gr Gold Dot, .950" OAL, CCI SP, SA 1115 FPS, SD 27, ES 70 - G42 AW Brl
    WSF - 5.0 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1126 FPS, SD 17, ES 48 - G42 AW Brl
    WSF - 5.2 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1141 FPS, SD 22, ES 56 - G42 AW Brl
    WSF - 5.4 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1174 FPS, SD 19, ES 44 - G42 AW Brl

    I will post the #5 and W572 results later if I have time. neither was near the max, so results were pretty pedestrian. I got as high as 5.4gr with #5 and 5.2gr with W572 and neither was pushing pressures much at all. The W572 loads were still scorching the cases at 5.2gr.

    *******. 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. *********************

    How long is your barrel, that is some pretty good velocities.

    Since this is for carry and won't be reloaded, you plan on 1200 fps +?

    It is stock G42 length, just a little tighter in the chamber and likely the bore, over OEM.

    Actually, I will continue to carry the UW +P XTP. This is just to simulate their loads for practice at a more reasonable cost per round (a lot more reasonable). I shoot a lot each practice day and want ammo that is very close to my carry load recoil and POI wise, I just need that at prices that won't break the bank. I will reload the Starline I am loading to these levels, just not at these levels (at least the ones I am shooting through the AW barrel. Any smiled brass gets chucked. I did the same thing with my nuke 10mm loads, one time for the new Starline at max effort, then they went in the plinking bucket.

    I do plan on getting just over 1200 fps for my normal practice load, because that is what I get with the UW loads. I also will match the XP and XD offerings, although right now I am satisfied with the XTP bullet.

    Comparing wound cavities are a little sketchy after the block has been compromised. It really should be individual shots on individual gel blocks.

    I've shot the (same bullet) Underwood loaded 65gr XD loaded in 357 Sig at 2100 fps out of a 3.4" G33. That's a pretty impressive round.

    Sounds like a plan Willy. The XTP is a fine bullet.

    Here are the results for AA #5 and W572. I will probably load a few more flights of W572 and go up until I start to see some pressure signs (I will need my OEM barrel along for this.. ;)). W572 is a little slower than WSF, but may have enough energy density to get up where I want before running out of room.

    I am loading all of these on my Dillon powder drop on my 550B. One of the things that is pretty easy to see is the SD and ES are bigger with W572 as the flat balls are bigger with this powder, even larger than WSF, so metering is not quite as consistent.

    As I stated in the WSF results above, I forgot my OEM barrel at home, so all of the following is with my stock length Alpha Wolf barrel.

    Both #5 and W572 seem to have a lot more headroom left, but I won't know for sure until I get the OEM barrel in the loop and start checking for smiles. As noted previously, the AW barrel just doesn't smile cases, at least at any pressure I have run up to yet. Primers looked great good at max for both #5 and W572, as stated earlier, at my highest rung today, I was still getting scorched cases big time from 572, it just wasn't sealing very well.

    W572 - 4.6 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 977 FPS, SD 45, ES 106 - G42 AW Brl
    W572 - 4.8 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 984 FPS, SD 52, ES 134 - G42 AW Brl
    W572 - 5.0 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1062 FPS, SD 25, ES 60 - G42 AW Brl
    W572 - 5.2 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 1099 FPS, SD 13, ES 37 - G42 AW Brl

    AA #5 - 5.0 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 909 FPS, SD 17, ES 42 - G42 AW Brl
    AA #5 - 5.2 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 957 FPS, SD 28, ES 62 - G42 AW Brl
    AA #5 - 5.4 gr, 95gr PD FMJ/FP, .985" OAL, CCI SP, SA 983 FPS, SD 17, ES 44 - G42 AW Brl

    I suspect #5 just isn't going to get there as we are pretty far away now. With W572, I could see a real turn in the curve when I went up to 5.0gr. I think we very well could get there with a few more turns. I have a lot of W572 around (like 7 lbs), so it would be nice if it turned out working as well as WSF (which I am down to a single half pound).

    Will be interesting to see the XTPs thrown in the mix. I too believe that AA5 isn't going to make it.
    I know it's a different ball game, but if you want more powder volume and are pushing the pressure envelope, you could burnish your bbl with boron nitride to reduce pressure. Also makes cleaning a lot easier.

    I think for the powders that are going to get the job done, a little extra pressure is a good thing. The slower burners seem to need the pressure just to start burning more cleanly and consistently. I think with BE86, WSF and maybe W572 there will be plenty of headroom for the target 1200fps and not be bending things.

    Yep, you're getting it done for sure. Mag primers could help light up the slower burners too.

    I have heard that, but my own experience is less clear cut. I do think for some of the most difficult powders to ignite like W296/H110, magnum primers help. Also, in large capacity cases of slow powders magnum primers seem to make a difference. I suspect for a case like the 380 the results may be immeasurable.

    Good possibility with such a small volume of powder. 296 in a mag case is a different game for sure.

    BTW Willy, did you get your chronograph fixed? Would be interesting to set them both up and compare the results.
