9mm Load Data Needed

    Can someone suggest some load data for 9mm 115gr FMJ (including OAL). My Lymans book only has JHP for 9mm 115gr.

    I've been loading 45.ACP only so far and now am going to do some 9mm. I just got some new dies (lee).

    Anything I need to be aware of (besides the obvious) when switching to 9mm from .45

    Hogdon/Winchester load data on-line for one
    See Alliant and other powder sites for more load data..

    I have the Hogdon/Win data as a PDF file and don't know how to attach it to my post. Tell me how and I'll give you a copy.

    9mm is of course a smaller case so OAL/pressure becomes more critical than that big 45 acp case.
    The 9mm case is straight, BUT tapered out from top to bottom. A good taper crimp just closes the bell the powder die gives. Approx. .377 to .378 works nicely. The finished round will have a slightly "coke-bottle shape". I for one like the LEE 4-die set with the FCD. The bullet seating/crimp die can be used to crimp or not. The FCD gives a fairly full-length sizing to meet SAAMI limitations and can be used to crimp on the last die..

    The typical FMJ is the easiest to load in 9mm. Depending on the pistol, they can be be finical about flat-tip, conical nose or JHP if your chamber is 'tight'.

    An easy powder to start with is Win 231/Hp38 because it gives a "wider" load range than many powders like titegroup and actually shoots very well. At light loads it's "sooty" but still shoots well.. After your comfortable with 9mm, try some other powders that may perform better for your individual use.
    In my opinion (others not) the 9mm prefers 124/125 gr bullets for less recoil and flip. YMMV

    Hope this helps.

    My favorite reference load is 115 gr FMJ with 4.8 gr of W231/HP-38 at 1.125"-1.135" OAL.

    Of course, you should always do your own full work up for your pistol/barrel.

    When I can't find load data particular to FMJ bullet, I will often reference JHP load data and conduct my own full work up from the start charge. Alliant load data don't list start charge, but I will use 10-15% below max as my start charge.

    Here's more from 2004 Alliant Load Data - http://glarp.atk.com/2004/2004Catalogs/2004AlliantPowderSM.pdf

    Figure out what OAL works in your pistol before you load a bunch. I have to load 124g at 1.06 to get them to feed in my CZ. Just take the barrel out and do the "drop test" to see what fits the chamber.

    You left out that it is a JHP or FT or Conical nose bullet you're talking about.
    CZ will easily feed 99.5+% of 124 FMJrn @ SAAMI MAX length.

    Anywhere from 4.0 to 4.8 grains of Titegroup works well for 115gr FMJ's. I've tried AA#5 as well but I don't have nearly as many loads done with that powder and I don't have the load data with me at the moment.

    All jacketed bullets of a given weight are loaded the same EXCEPT for the COL. COL is very critical in 9x19 and .40 S&W. Read your manual and learn how to determine the optimum COL for a given bullet and your gun. Remember the COL is manuals is the minimum you should use with the data.
    The world is full of loading data. Use Hodgdon, Alliant, Accurate, and Ramshot web sites for data.
    Buy at least two manuals and read them so you know what you are doing.

    Well I guess I'm just the lucky .05% then because mine won't feed MB 125 LRN, or 124g Rem Golden Saber unless I load them to 1.06 and it takes 1.035 with Sierra 125g JHP

    My point was he should check the OAL that works is his gun for the bullet he's loading.

    Viht also publishes data online. They have data for Rainier plated too. The OAL is important with 9mm because of so many different bullet types. The powder, if you work up, is similar for any weight. Hornady will give you data for one or two calibres if you call and ask nicely.

    If you get the Loadbook for the 9mm though, you are all set. They come in calibre specific booklets, each calibre has data from several bullet makers and several powder makers for thousands of loads overall. I have them in 9mm, 10mm/.40, .223, .308, .45ACP, and .357/.38. They go for $5-$7 each.

    If you have a specific load or loads you are looking for, let me know what you have, PM me, and I'll look those up for you.

    I don't know what brand / style FMJ you are using, but I can provide you with at least a few FMJ OAL's.

    I have Sierra & Hornady 115 gr. FMJ data showing 1.100". and Speer's 115 gr. TMJ @ 1.135".

    I shoot the 115 gr. JHP with 6.2 grs. of HS6 and performance is very nice I feel. I also load with Longshot, but I prefer to use it with the 124 gr. and up bullets.

    I made up some dummy rounds with no primer/powder with OAL around 1.155. The max OAL in the SAAMI specs is 1.169 and the factory rounds I have been using run around 1.158. I used the "drop in the barrel test" and the rounds fit perfect like the factory ones.

    I then created some charged rounds using 4.2gr of 231 (the range in the charts provided with my Lee dies is 4.2 to 4.8) and the same OAL as the dummy rounds (1.155). I figure I should be good to go.

    Be sure you do function check test by manually feeding the rounds from the magazine and releasing the slide (do not ride the slide with your hand).

    Barrel drop test will give you MAX OAL for your barrel. You then need to determine the IDEAL OAL that will reliably feed/chamber.

    Then you need to determine the powder charge that will reliably cycle the slide while producing accurate shot groups. For my pistols, 4.5 gr will start to reliably cycle the slide with 4.8 gr producing more accurate shot groups.

    The hollowpoints agree with what I said. Your MB-LRN is why I said 99.5%.;)

    The drop test gives an oal just touching the rifling. Subtract around .015" from that to get a workable oal that allows for press and bullet variations.

    Is that for Win 231?
  16. bds

    bds Well-Known Member

    Yes, W231.
  17. MoreIsLess

    MoreIsLess Well-Known Member

    I'll have to try that. I've been using about 4.2gr, I'll have to up it tp 4.5.

    Could you elaborate on how to do the MAX OAL test:
  18. bds

    bds Well-Known Member

    Walkalong illustrates determining MAX OAL well in this thread - http://www.thehighroad.org/showthread.php?t=506678

    Essentially, with the barrel out of the pistol, your test round should fall in the chamber freely and spin without hitting the rifling.
  19. MoreIsLess

    MoreIsLess Well-Known Member

    I assume that after finding the MAX OAL that finding the IDEAL OAL is more or less trial and error, i.e. what OAL produces the best results on the range, eh?
  20. bds

    bds Well-Known Member

    Trial and error? no. It is a deliberate process of MAX OAL - IDEAL OAL - Powder work up.

    Once you determined the MAX OAL using the barrel drop test, next you determine the IDEAL OAL.

    Load the dummy round (no powder/primer to prevent accidental discharge) at MAX OAL in the magazine with the slide locked back. Then release the slide (do not ride the slide with your hand). If MAX OAL feeds/chambers reliably from the magazine, then you can move onto powder work up from start charge.

    If the MAX OAL doesn't feed/chamber well, then you'll need to incrementally decrease the OAL (say by .005") until you reach an OAL that will feed/chamber reliably.

    Once you determined the IDEAL OAL, then start the powder work up from published start charge and load 10 rounds of each in 0.1 gr powder charge increments. Range test the test loads to determine the powder charge that will reliably cycle the slide and produce accurate shot groups.
