    Thanks, gang. You confirmed my suspicions that it was a "last resort" sort of idea. I'll pick up some lighter bullets for the .380 when I have opportunity.

    Bumping this rather than creating a new thread.

    I'm sending off GSSF paperwork for a 42 so I'm looking at .380 loads now. I'm looking at SNS casting 95gr coated bullets, and I have Bullseye, WST, Red Dot, and Power Pistol on hand.

    You're in luck, because there's load data for all of those except WST.

    http://handloads.com/loaddata/defau...&Weight=All&type=Handgun&Order=Powder&Source=

    I've been using Promo and tried titegroup. I might try titegroup some more...but I have 2lbs of it and 16 of Promo.

    I ended up buying an XS powder bar for my RL550B to try to get better consistency with <3gr charges of Promo. It seems to have helped.

    Hadn't looked at that website yet, thank you. Looks like I'm in business whichever one I want to use.

    What's your preferred OAL for the 42?

    I'm still trying to figure it out...and it depends on the bullet. For Xtreme 100gr FP, I think I've been loading about 0.935". It's a short bullet and needs to be loaded short to have much bullet inside the case. I'm also trying Bayou 95gr. I wasn't entirely happy with the first batch of them I loaded, so I loaded some more with more powder and shorter OAL, but haven't been able to test them yet.

    AJE "...I'm looking at SNS casting 95gr coated bullets, and I have Bullseye, WST, Red Dot, and Power Pistol on hand."

    For target loads I have settled on "Magtech" bullets, specificly 95g FMJ RN. They are fairly inexpensive, consistent, load well and I have had some great rounds using these bullets.

    My load with Bullseye I use 3.2g
    OAL I use .975
    Velocity runs at 859.2 fps out of a 3.5" barrel

    With Power Pistol I use Hornady's 90g XTP HP bullets

    Power Pistol - 4.2g
    OAL - .965"
    Velocity - 887.3 fps again out of a 3.5" barrel.

    I have not test the other two powders you have but for target loads Hodgdon Universal, Accurate Arms #5, Winchester AutoComp and of course Winchester 231 work very well in 380.

    Good luck and have fun with your new G42.

    The longer bullets pass the gage and barrel test in my G42 but do not chamber reliably. I need to run an OAL shorter in my G42 than my Sig.

    I got a G42, and my wife liked it so much she now has one as well. Both guns have Trijicon HD sights. FWIW, the HD sights print about 3" higher at 50 feet to 25 yards than the stock sights.

    I have several hundred rounds loaded with 95gr FMJ-RN and 3.0 gr W231. These loads ran fine in my Ruger LCP, but wouldn't run in the G42. Not enough juice.

    I loaded 50 rounds today with 3.3 gr 231 and the same bullet (oal .975"). These ran fine shooting two handed, but one handed drills gave malfunctions. Tried the same drills with PMC Bronze FMJ and Fiocchi FMJ without problem. So, it seems I need yet more juice.

    Since several sources list W231 max at 3.2 to 3.4 with 95 gr FMJ, what powder WILL give me enough power to safely operate? Thanks!

    I have several hundred clean empty brass cases anxiously waiting to be filled.

    I recently purchased a G42 that is quickly becoming my wife's favorite. I just ordered the stuff I need to upgrade my Dillion RL 550b so I can load .380. I also intend to use W231 so I am very interested in your results. I have read in two different places that the Speer numbers are 3.6 to 4.0 for FMJ 95G. I don't know anything else about the data, so I am going to get the book to check it out. That is quite a bit more than my Lyman manual recommends. However, if the Speer info turns out to look good all the way around, going up to 3.5 or 3.6 might fix the problem. I'll keep you posted on what I find. I also just ordered The Complete Reloading Manual for the .380 A.C.P which compares the data from a number of sources. I got that one for .40 cal years ago and found it to be pretty helpful.

    I had a load for my G42 that worked well but ran out of powder.
    100gr PFN Xtreme 3.1gr W231 OAL .940"
    100gr PFN Xtreme 3.2gr No.2 OAL .940"
    Now I have Unique,WST,No.5 and Titegroup. I will have to work up a good load for one of these powders.
    These guns are picky on the loads. We have two Thunder 380's and a soft load will work in them!

    2.9-3gr Titegroup with that bullet/OAL should work.

    Thanks for the info. I had my reloading manuals out and was looking at that load!

    Just received notice that the Hornady 90gr XTP that I've had on backorder since before SilencerCo released "The Wizard" have finally shipped. :dancing: I'll be putting together loads for the P238.

    I just got to shoot my 42 after glock reworked it w/ updates.
    I ran few factory and no issues as before FTF's.

    I had Red Dot on hand and my load was 2.5gs, 95g cast boolit and OAL of .975 &.980
    No crono,indoor range. No FTF, pretty good groups to fer a stiff trigger.

    PLEASE NOTE ! RED DOT does not meter well and if you have never used it before check all your powder throw weights till you can be sure it's consistent .
    I believe 2.6 was max( going by memory now) .
    My Lee powder measure was not consistent at all, my Dillon SDB measure was pretty good but not 100% trusted as with other powders. Did not try the rcbs measure.
    Also just FYI, I find my PACT electronic scale at such low weights can NOT be trusted and certainly not good for trickling light powder loads.
    Checking the calibration with heavy weight does not mean its dead on at really light weights.
    I had this issue long ago when using titegroup with light loads.

    Be safe always and good shooting,

    Mike

    I've been loading 2.7gr Promo (Red Dot compatible:) with 95gr Bayou bullets.

    I bought an XS powder bar, because I wasn't happy with how the Dillon small bar was throwing charges this small.

    I don't trust my Lyman digital scale at all, but I know it's worse at really low weights. To get a number I even believe from it, I always combine 5 charges and divide by 5. Then I move the powder over to the Dillon beam scale and see what it really weighs.

    Your powder and bullet weight please. I'd love to try it as I have some #5 on hand. Usually I use 3.2gr of #2 with 100gr extreme bullet.

    I'm not familiar with promo. Does it look the same as red dot ?
    How do the charges drop with the XS powder bar now ?

    I'm sorry you have the same scale trouble as I have. I thought it was because my pact is an older model. It's a little slow returning to zero after I weigh a charge. It can fluctuate .2 , if I wait a bit it changes again .1
    I went to the extreme of moving it to another location, no air fan or lights around it, on a flat level surface and the same happens.
    I wonder if your is made by same company that makes pact ?

    Be safe and double check always !
