    I currently have 2000/9 MM 124 grain FMJ bullets and can only find one recipe useing WSF powder.

    My question is can I use a recipe useing the 9 MM/125 gr. bullet that has many different powders you can use?

    I think you need to restate your question. There are many different powders with published load ranges for a 9mm 124 bullet. First you need to establish what type of load you want to develop.

    If you are making "Target" rounds use Factory ammo as a template or standard for your numbers;

    Federal "American Eagle" Factory Ammunition
    124g RN FMJ
    Velocity - Box listed @ 1,150 fps /1,121.4 fps my 5 shot average @ 73 degrees
    OAL - 1.150"

    The Hodgdon Reloading annual 2012 has listed for the 124g FMJ bullet;
    WSF - 4.7g up to 5.3g (max vel. of 1,115 fps) - they show testing this out of a 4" barrel.

    WSF powder is a "medium" burning powder (#36 on the Hodgdon burn rate chart) which means - in my tests with 115g FMJ bullets, the powder charge on the med/high side worked out the best for me out of my G17 w/4.49" barrel.

    Most of my tests using 124g FMJ bullets with med/slower powders work best at an OAL of 1.135" Not the 1.169" listed in the Hodgdon Annual. Now again that's out of my G17... not your pistol.

    Start low and work up slowly with charge weight and OAL until you find out what your gun likes the best.

    I hope this will help you, good luck & be safe.

    1gr bullet shouldn't make that much of a difference assuming it is the same type bullet.

    That being said, I have been using the hodgdon data for WSF that you mentioned and it has been working very well for me for FMJ/CMJ bullets.

    4.8gr WSF, WSP primers, mixed cases, OAL 1.145" - getting 1050-1075fps and excellent function.

    I had un-burned powder at 4.7gr and 1.169" OAL (starting load in their data) but once I progressed to my current load that problem went away. Good and clean burn and clean powder overall. I think you will do well with the Hodgdon data.

    Go to the Hodgdon website. The now have the Winchester powders. Load Data with Wolfe Publishing has many recipes as well.

    1gr difference in bullet weight is insignificant. You can use 124/125gr recipes with 124gr bullets.
