    My load is:

    Mixed cases
    Rem or Win primers
    50/50 WW/PB + tin for 1.5% total
    Water dropped and sized to 0.357"
    4.0gr Unique
    COAL ???? (I'll check after work)

    Chronos at around 1050 fps.

    So far my favorite load has been:

    5.6 grains HS-6
    CCI 500 Primers
    Either the hollow point or penta pin bullets (haven't tried it as a solid)
    Cast of 50% WW and 50% pure with 2% tin added
    Sized to .358"
    Winchester cases (left over from firing WW white box ammo)
    Lars' 2500 + lube
    C.O.L = 1.130"

    My COL may seem a bit long, but they run fine in my pistol without any problems.
    I shoot these out of my SIG P225 and get zero leading and great accuracy @ 25 yards.

    I also plan on trying out loads using Unique, Blue Dot and AA 5.
    I have to wait until I get more use of my right arm and more feeling in my left hand 1st though. It seems my TBI and MS have conspired to temporarily (hopefully) take me out of action.

    All the other data will remain the same as to cases, primers, etc.

    I'll have to dig out my old chrony, camera and some gallon water jugs while I am at it.
    Might as well do it right !

    50/50 WW/Pb water dropped with 5.4 gr. of Russian Unique in the 9mm Largo. Mr. opposum never knew what hit him.
    45 2.1

    Knowledge without understanding is a dangerous thing. For a little knowledge entices us to walk its path, a bit more provides the foundation on which we take our stand, and a sufficient amount can erect a wall of knowledge around us, trapping us in our own ignorance.

    Never sleep, never die

    Knowledge is easy to get, but worthless if you never use it. However the info is free, so the only person you have to blame is yourself if you chose not to use the information.

    Here's one I use. I think oal was 1.10, water dropped wheel weight, lube was carnuba red, sized to .358. I tried several different powders, 231, universal, unique, bullseye, hs6, all leaded the barrel some less than others, then I tried 4756 and the load shown. All came together, the hi-point carbine really shoots this combo.

    Interesting. I wouldn't have thought of water dropping 50/50. I'm going to have to give that a go.


    That's a nice looking group with your HiPoint, Rusty. That's the sort of group I'm going to see if I can achieve with this boolit, but in my Glock. We'll see. Here's my benchmark, with Precision Delta JRNs.

    Here's BeeMan's post on the group buy thread. Thanks for posting, BeeMan.

    - Win brass, expanded with a custom m-die to ensure the .3585 bullet is not sized down after seating.
    - Fed 100 primer
    - 4.5 grains WSF, which is a mid range load per the Hodgdon load data center for a lead bullet
    - Miha 359-125 with round HP pins, air cooled wheel weights
    - Tumble lubed twice with 45/45/10, once before push through sizing to .3585, and again after sizing
    - Seated to 1.100 OAL, with a taper crimp that just straightens the bell on the case.

    Accurate to the limits of my ability. Zero leading after 50 rounds. A little powder and lube residue pushed out with a single patch of Eds Red and a couple dry patches. Feeding was flawless.

    Two comments:
    - Fit is king. Sizing .3585 just allows the loaded cartridge to chamber. The custom m-die made this possible, though others have used 38 special expanders, etc.
    - Powder burn rate seems touchier in the 9mm than in other cartridges. WSF burns slow enough to avoid stripping while using ACWW. A fast burn to bump up is not needed when bullet fit is correct.

    My preferred load giving much better accuracy than I ever achieved with jacketed or plated bullets

    Geco cases
    Magtech primers
    Water dropped range scrap
    BAC Lube
    Sized to 0.358"
    4.2gr VV N340
    COAL 1.085"

    Chronos at 1050 fps from a Smith & Wesson M&P9

    Did you simply choose an OAL that worked for your barrel and then just worked up the powder charge until you found accuracy or ran into a guestimated fps limit?

    I'm just curious since the only VV 9mm loads I can find always have a COAL of 1.142".

    Thanks. I just got in a pound of N340 to try, so we'll see how I fare.

    My latest combination is:
    Mihec bullet sized .358" cast from 50/50 Clipon WW and soft, air cooled.
    lotac or BAC lube
    mixed range brass
    I've used Wolf, Winchester, and CCI primers
    4.5g WSF
    OAL 1.115"

    Shoots really well in my STI Spartan, and a couple of Glocks (Shhhhhhh)
    I tried tumble lubing with 45/45/10, and got some leading, may try that again now that I have my sizing issues figured out.
