    Hello everyone,

    I will be setting up my new reloader tomorrow and although I do have a reloading book, I was looking to see what amount of Win 231 powder people are running with their 180 grain FMJ 40 S&W reloads. I know it's a long shot, but I figured I'd give it a try on here. Thanks!

    That's what I have in my book as well... 4.1-5.0 . Just didn't know if someone found that sweet spot yet in between.

    3.9 WW231

    3.7 and 3.9 grain WW231 180 grain Rainier FMJ OAL 1.125 are very nice.
    3.7 715 FPS for 128 PF. Groups nice and are very accurate.

    The "sweet spot" for you may be different for me....

    I really am happy with 4.2gr of W231 as it's fairly light, cycles my G23c fine, and is as accurate as I need it to be. With that said, my friends run much higher loads (read: just slightly over max) in their Rugers! So it's all somewhat subjective.

    You'll have to try some loads as the mechanics of your firearm are different from mine.... What works in mine may not work in yours.

    I do not use 231 but this is still relevant. I am working up a new load for my G35 and running my rounds across the chronograph a couple of days ago here is what I found:

    Increasing the charge by .2 grains increased FPS by 50.

    Changing the OAL from 1.13 to 1.12 increased FPS by 25.

    Changing the OAL from 1.12 to 1.11 increased FPS by another 25.

    All three loads were pretty accurate, but the OAL of 1.11 was the most accurate and the one that hit clsest to POA.

    I still need to change things more because the 1.11 OAL load is still about 50 FPS below the needed velocity of 900 FPS that allows me to shoot major PF in USPSA.

    I have already worked up a new set of loads where I increased the charge by another .3 grains and have loaded 10 rounds each at 1.13, 1.12, and 1.11 OAL.

    I will run these loads across my chronograph tomorrow and see which one is the most accurate and still makes PF. My guess will be the 1.13 OAL because the change in charge combined with OAL will probably make this the round that shoots closest to POA.

    Reloading is very much a trial and error situation because the bullet weight, profile, case, primer, powder, charge, OAL and the weapon it is being fired out of all combine to make it impossible to have a one size fits all load that shoots the same for everybody. Just to many variables involved.

    Well there ta go three different loads to try out. I shot well over 10 K of that load for IDPA and several classes. It is accurate makes power factor in a G23 and is fun to shoot. I use something different now but not a good beginners load. Go load my two and sellersm and see which one you like best.

    have fun.

    Thanks so much for the help thus far, greatly appreciated. I will have to play around with it a little I guess. Start low and work my way up. I will try some of the suggested info.

    One of the problems I think a lot of reloaders have is the need to work it on up. Everyone seems to want to see how hard they can run a load. That puts a lot of unneeded wear and tear on both them and their guns. Start low find a load that cycles your gun. That is your base point. From there work it up looking at accuracy. when you find a real accurate load stop! Really look for a sweet spot and not just for how hard you can run your gun. The vast majority of KB are caused by guys loading their pet loads to hot!

    That's the exact opposite of what I want to do. I do just want a light accurate load to keep wear and tear off my gun. I ended up using 4.4 grains. Loaded 20 rounds and went to the range. Everything felt perfect. I think we have a winner.
