    Default Win 231 in .45 ACP... Recipes?

    I've been poking around for a good load for Win 231 for a 230 gr FMJ load. Winchester lists a max charge of 5.3 on their site but in searching I see a lot of loads that seem to be way higher than that. Did they change the formulation or something? I'm also guessing it's just winchester being cautious. I'd like to end up with a load that does about 830-850 fps out of a 5" 1911, so I can use it for pins. The CCI Blazer brass load I typically use clocks in around ~850 or so.

    I've been loading up .45 ACP with Unique for awhile, but I got a can of 231... I think it meters a bit
    better. Unique is kinda fun though, watching the numbers bounce all over the place on the chrono, and getting your
    arms covered with unburned powder flakes.

    I've been using 5.2 grns of W231 over Berry's 230gr FMJ. I think this will be a little light for the FPS you are trying to achieve. Out of my S&W 1911 I get the following results with this load.

    761
    779
    740
    750
    751
    761

    Average of 757
    Power Factor = 174
    13% Standard Deviation

    This is good enough to make major with a little extra. It's accurate for me so I haven't messed with it much.

    5.5 grains of W231 gets me to 800-850.

    231 is fine for .45 ACP, but I think WST is cleaner and the loads are nearly identical. Then again, compared to Unique, anything this side of black powder is cleaner.

    WST used to be cheaper, too.

    WOW- this isn't out an auto though is it? 230gr??


    My S&W 1911 give me a chrono average of about 720 ft/sec with Berry 230gr RN bullets!!!


    I've been REAL close to power factor at some matches!

    And yes... I too have seen bigger loads... no idea why they suggest 5.2gr as the max!

    Let me add to the confusion. This is the data for 230gr using W231 from Handloaders.com

    FMJ 5.7 gr Win 231 830 fps Winchester

    Thanks for the help guys.

    I ended up making myself a "Variety pack" ranging in loads from 5.0 to 5.5 grs
    of 231.

    I'll start with the low one through the chrono and go up from there to see how
    it does.

    I now use 231 in .45 acp after using Unique for years. I find 231 to meter better and it is much cleaner. Following are loads that I chronoed out of a 5" S&W 1911. I do believe that Winchester's data is very conservative. Many older manuals list loads even higher than what I show here. All these loads were perfectly safe and showed no pressure signs or problems of any kind in my guns.

    230gr LRN LOA 1.260" 5.1 231 = 781fps
    230gr LRN LOA 1.260" 5.3 231 = 827fps
    230gr LRN LOA 1.260" 5.6 231 = 870fps
    230gr LRN LOA 1.260" 5.8 231 = 907fps (personal max) good pin load with 225 FP

    With a Hornady FMJ 230 I get the following:

    5.6 231 = 831fps
    6.0 231 = 872fps (my personal max with this combo)

    I substitute a lead 225 flatpoint for the 230 RNL for pin shooting and get very similiar numbers. Cast lead bullets, in my experience, always shoot faster than a jacketed bullet of similar weight and with a similar charge. Infact, I always use less powder to reach the velocity I want. See that I use 6.0 of231 with a FMJ to get to the same speed as 5.6 231 with a cast bullet. This has proven true in every case and with every caliber I've ever loaded and chronoed. Flat point was loaded to 1.210".

    I have shot 255 gr LSWCs and 250 gr cast cowboy bulllets (RNFP) with 5.6 gr of 231 and achieved 847-877fps depending on bullet brand. In theory these should knock pins over better than the 225 flat points at 907fps, but if there is a benefit I can't notice it. And I think the 225 is easier on your gun's frame. I stick to the 225's even though the heavy 250+ bullets are interesting. Hope this helps.

    What LOA do you load the 230 FMJ to?

    Just loaded up a bunch of Ranier 185g plated hollow point target loads using 5.8 grains WIN 231. Haven't had a chance to check them on the chrono yet.
