    I just picked up 500 9 mm Hornady 115 gr RN/FMJ #35557 bullets. All of the data in my manuals for the 115 gr bullets pertain to HP's.
    Does anyone have specific data for this bullet? I have Win 231 that I would like to use. I also have WST and Unique.

    Thanks for any help.

    You can use the 115gr Speer Gold Dot load data from the Hodgdon Powder web site just fine. W231 is probably going to be your best powder choice. Just begin at the "starting load" and work up. You might even stretch the OAL by .010-.015".

    Here is what Hornady has published for #35557:

    Win 231 4.1 grs. - 4.5 grs.

    I don't see anything published for WST any where.

    My advice would be to go with Unique because it has a slower burn rate, thus a larger load range. This will equate to less pressure management issues during load developement.

    Sierra shows a range of 4.9 grs. - 6.6 grs. (Unique)
    Nosler is 5.1 grs. - 6.1 grs. (Unique)
    Speer is 5.6 grs. - 6.3 grs. (Unique)

    Use any 115gr jacketed bullet load found in your manual with your fmj's. The powder companies will usually have free data for 115gr FMJ's on their websites. Most manuals lump data for like weight bullets together, the only difference is the loaded cartridge OAL as JHP bullets have generally shorter OAL than RN bullets as the JHP bullets are generally physically shorter.

    From 1999 Winchester load data - http://www.thehighroad.org/attachment.php?attachmentid=159609&stc=1&d=1329800605
    From 2004 Alliant load data - http://www.google.com/url?sa=t&rct=...sg=AFQjCNHnWLp5LTU0YIrdLKjtAjtiKft_jg&cad=rja
    For Winchester 115 gr FMJ bullet, I use normally 1.125"-1.135" OAL and these OALs work well in most pistols, but do a barrel drop test (finished round should drop freely into the chamber with a "plonk" and spin without hitting the rifling) and function check by loading from the magazine and manually releasing the slide to ensure reliable feeding/chambering.

    My reference 9mm load is Winchester 115 gr FMJ with 4.8 gr W231/HP-38 at 1.135" with .375" taper crimp. It is comparable to Winchester white box and more accurate.
