    Im looking for some suggestions on some powder and bullet suggestions for plinking. Any good ones?

    These 9mm loads work well in my Glocks:

    115gr Winchester FMJ, 4.9gr W231/HP38, 1.125" OAL.

    125gr Plated/Lead RN, 4.3gr W231/HP38, 1.125" OAL

    I get tighter groups with mastercastbullets 124gr tc's over RDot than most jacketed slugs in my 5906 S&W.

    I have been using 115gr FMJ with 7.7 gr of blue dot---mild & accurate out of my P-35
    Browning----it may be more my 1,5 # trigger than the bullets..................LOL

    I use Missiouri bullets 125gr LRN "small ball" over 3.8g Red Dot. Shoots very accurate and functions all my pistols without beating them, me or my brass up.

    bds' recommendation on HP38/WW231 is also a good one that I've loaded very similar to in the past.

    I use the following:

    Case: S&B
    Primer: Winchester small pistol
    Bullet: 121 grain Zero JHP, Be aware that this is a .356 38 super bullet that works well for me but some may say not to use them.
    Powder: 4gr of VV N320, it is more expensive but is by far the cleanest burning powder I have ever used.
    OAL: 1.1", I realize this is short but my CZ requires this due to the extremely short lead in the barrel.

    This load is a mild minor PF load for me out of my gun, but I would advise starting at 3.5 grains and working up.

    I load a lot of Missouri Bullet Company 124 LRN over the top of Ramshot Zip.

    Works great for general purpose practice rounds. For jacketed I use bullets from Roze distributing.

    WCC MilSurp brass
    Remington 1 1/2 primers
    Remington 115 FMJ bullets
    HS-6 powder
    And work up carefully to somewhere in the 7.0-7.4 grain range.

    I get +P+ velocities (1325-1350 FPS) at low end +p pressure levels (judging pressure by the number of times I can reload the case before the primer pockets start to loosen)

    115gr. Montana Gold FMJ or HP, 4.7gr. W231, 1.11" (RN), 1.07" (HP) OAL. Works in everything I own, from plastic pistols to Hi-Power. It's as accurate as I am. Been putting together that load for upwards of 20 years - at least with that weight bullet, if not a Montana Gold.

    Well I found some plated bullets made by some company called Barry's at 115grains and picked up some W231.

    How does 4.6 grain sound to start off? the Winchester reloading site is a bit confusining because they list 2 different bullets only @ 115 grains; the first one is a Lead Nose round (4.3 to 2.8 grains) and another one that I have no idea what the code stands for is "SPR GDHP", whatever that is, its listed at 4.7 to 5.1.

    Which one should I pick?
  13. bds

    bds Well-Known Member

    Referencing the Winchester website for W231 for 9mm, load data for Lead Round Nose reads 4.3 to 4.8 grain with 1.10" OAL.

    SPR GDHP = Speer Gold Dot Hollow Point.

    I normally load 5%-10% below max load data for lead/plated bullets. Also, note that 4.7 to 5.1 grain for jacketed bullet is with the longer 1.125" OAL.

    You should be fine starting at 4.6gr for 115gr plated bullets. Have you determined which OAL feeds/chambers well for your pistol from the magazine?

    Have you determined which OAL feeds/chambers well for your pistol from the magazine?

    Im glad you brought this up - on my rifle I use a hornady OAL gauge that I use to determine the OAL of the cartridge, but on this pistol Im running kinda blind! I had some American Eagle ammo that I used in it a couple of days ago, which ran flawlessly, and I measured it to be 1.14-1.15" so I thought I'll go with that length. Is there a better way to determine the OAL in a semiauto pistol?

    I usually start with a couple of dummy rounds (no powder/primer) with the usual OAL for the particular caliber (9mm/40S&W = 1.125", 45ACP = 1.25" OAL) and check the feeding/chambering from the magazine by releasing the slide by hand .

    If the dummy rounds don't feed/chamber well, I gradually decrease the OAL (say by 0.005") until I have reliable feeding/chambering.
    Once I have reliable feeding/chambering OAL, then I move onto making test loads starting with 10%-5% below max load data.

    * This usually works for FMJ/lead round nose, but for some lead bullet weights/profiles and JHPs, you may need to decrease/increase your OAL.

    Here's walkalong's link to determine MAX OAL - http://www.thehighroad.org/showthread.php?t=506678)

    +1 for Walkalongs OAL method.

    For jacketed straight case rds (9mm, 40 cal etc.) use a fired case that hasn't been sized.
    Gently push 'your' bullet into it a few thousandth's.

    With your barrel removed, push this case and bullet into your chamber steadily until the case mouth seats.

    Gently remove and measure the oal.

    Do this with a couple more cases to check consistency.

    This will give you the oal that will "touch the leade/rifling" for THAT bullet only in that gun.

    Shorten this by .005 + the max variation of your press. If your press loads within +/- .004, the .005 + .004 = .009--call it .01 to subtract from the oal test.

    If the test gave a MAX oal of 1.160 for an MG 124gr FMJ, then (with that bullet only) your max loaded cartridge length should be ok at 1.15" or less.

    With a dummy cartridge loaded to that length, you should be a able to drop the round in the chamber, hear it seat on the case mouth, and then be able to rotate the cartridge by hand. If it will rotate, it's not touching the rifling.

    Do this test for each type & brand of bullet you use. JHPs will test way shorter.

    125 gr. SWC's cast & sized to 357 pushed by 6gr. VV 3 N 37 is working real nice for me in both my P226 and my G17 with KKM barrel.

    Well I tried 115 grain jacketed bullet (Barry's) with 4.7 grains of W231 behind it (according to the book max is 4.8 grains) and the OAL was 1.15".

    Compared to the store bought American Eagle (115 grain bullet), my handloads had FTE, especially the last one in the mag. The brass usually getting caught between the slide and chamber. I noticed that my handloads had the brass ejecting straight upward instead of to the 3 o'clock position.

    Should I increase the charge or just seat the bullet deeper and keep the 4.7 grains of W231?

    That's sign of not enough force to push the slide all the way back.

    Which gun are you shooting your reloads out of? Some guns (like Glocks) have stiffer recoil spring and require near max loads out of 115gr 9mm to cycle the slide properly. I seat my 115 gr FMJ bullets down to 1.125" OAL and use 4.8-4.9gr of W231 to get the slide to cycle properly.
