    While posting for another thread, I realized I forgot about this Promo thread. I tried to update the Promo range test thread, but the forum rule won't let me.

    So, starting a new Promo thread to continue posting my range test results (Here's the old Promo thread you can refer to).



    To bring you up to speed, my Promo testing went well for 9mm & 40S&W using various jacketed, plated and lead bullets but had issues with the initial 4.0 gr load with 200 gr SWC. I figured out what was happening with the PT145's shot groups with the lead loads. Turns out the bore was slightly oversized and the light 4.0 gr load was not properly bumping (obturating) the bullet base (and that's why the 5.0-5.5 gr W231/HP38 loads were shooting fine). I ended up ordering a good stock of 12 BHN SWC so I am good for testing light loads again. :D

    My pursuit back to a 1911 with CA legal Dan Wesson Pointman 7 was temporarily put on hold with 200 units/year production limit ... darn ... but wife got me a S&W M&P45 for Christmas to ease the pain.

    With the .451" bore size of the M&P45, 4.0 gr of Promo with .452" sized Missouri 18 BHN 200 gr SWC did much better:

    45 ACP average shot groups:
    200 LSWC/4.0 gr - 7 yard 3/4" - 10 yard 1" - 15 yard 2" - Mild recoil

    At 7 yards, this load kept producing single hole shot groups. Below are pictures of average 10/15 yard shot groups. This load has become a favorite of my wife due to mild recoil and good accuracy (the small grip insert for M&P45 fits her hands very well). I hope to continue with more Promo load testing with bullets/powder charges I specified earlier in the thread.

    I did a similar experiment and posted the results on the OFCC forums:

    4.0 gr charge for 200 gr 45ACP load that is accurate? Cheap indeed.



    This is what Alliant's website says about Promo:


    I based Red Dot load data for my Promo test loads but weighed the test powder drops from Pro Auto Disk to determine the Auto Disk hole to use (I did not go by the Auto Disk chart for Red Dot).

    Alliant currently publishes 12 load data for Red Dot in pistol/revolver calibers. Here's a sample load data for 38 Spl and 45ACP:

    SteveC posted the following older Alliant's online load data for 9mm in another thread:

    a good write-up. I just ran out of my stock of Red Dot which gave me best results with cast slugs in several different chamberings from .32acp to .45acp.
    I'll likeley give promo a try, it appears it's even cheaper (if that's possible, seemed like a lb of RD last me forever) than RD!
    however everything I read concerning RD was to use much caution when approaching max which I did as MOF. all my 'plinking' loads are cast slugs a bit under the max data - about 5% lower.

    Did some 15/25 yard testing with 45 Herco loads (for another thread) and shot some of my reference 200 gr SWC loads with 4.0 gr Promo for comparison and decided to update this thread.

    Previous 10/15 yard testing was done with M&P45 with a trigger job done by me using the Burwell pdf. This time railed Sig XO TacPac 1911 was used with 12 BHN 200 gr SWC (Bullseye #1) loaded to 1.240"-1.245" (any longer than 1.245", bearing surface of the bullet base will hit the quick start of rifling) at 15/25 yards.

    15 yard group measured 1" and 25 yard group measured 2". The Sig 1911 has 7000+ rounds shot through. I think not bad for a "plinking" load.

    For some reason, ATK/Alliant removed the 2004 load data pdf from their servers last year.

    Unless you downloaded a copy, I don't know of a current official download source and after failing to locate an official source after Googling for it, I uploaded the pdf to THR server for downloads.

    Since current online Alliant load data is quite limited, 2004 Alliant load data is an invaluable reloading resource for many popular Alliant powders, especially for FMJ/RN and lead bullets.

    I was one that saved a copy before it was taken down from GLARP.ATK site...

    I had been pointing people there for a couple of years...I now point them to your upload...

    The copy of the 2005 manual at CastPics has the same data, but the quality is pretty bad...

    If you want another shocker, American Select performs like Bullseye with 200 gr. bullets.

    I keep hearing good things about American Select and plan to test it in 9/40/45 when I am able to buy it. Another powder I am looking to try is Solo 1000. Sure looking forward to the end of "powder shortage".

    The only positive of the great pistol powder shortage has been my discovery that Promo makes a great powder for 40S&W and 357 Sig midrange target/practice loads.

    These days, whatever I can find is a great powder.

    While I found published load data for American Select and Solo 1000, I was not able to find any published load data for 20/28 for 9/40/45 calibers.
