    Using jacketed bullets, what are some good subsonic reloads for 9mm. Have Unique, Clays. Bullseye , VV N 310 & N 320, & Tite Group powders.

    What bullet weight?

    In Speer #14, every 147 gr max load is less than 1126 fps as are many starting loads for 115 gr or 124 gr.

    I would probably try for something in the 1000 fps range.

    Most of my 124gr loads and all the 147s are subsonic. I haven't used any of those powders...just Universal, WST, and Longshot...which doesn't sound subsonic...but is. :)
  4. I use 320 and searching this forum for "320" will get you some recipes.

    3.5 gr N320
    147 gr MG CMJ
    1.135 OAL
    Starline brass
    Crimp .3775
    Fed SPP
    ~882 fps (G17)
    129.65 PF

    They are accurate out to 75 yds, and really accurate to 35 yds. I use them for all disciplines that I shoot 9 mil in; IDPA, Steel, GSSF. They work fine in my G26, G17, G34.

    I stole this recipe from a shooting buddy, but it works well, especially suppressed, from my Glocks, 9mm AR, and MP5.

    147 gr Berry's RN
    3.3 gr. VV N320
    CCI 500 primer
    1.135" OAL

    Ave. vel from G17 - 871 fps
    Ave. vel from 9" MP5 - 927 fps

    I've also worked up a 124 gr. "subsonic" load. I say "subsonic" because every once in a while I will have one go supersonic, and it is definitely louder with a suppressor than the 147's above.

    124 gr. Power Bond bullet
    4.0 gr. Hodgdon Universal
    CCI 500 primer
    1.135" OAL

    Ave vel. from G17 - 1002 fps
    Ave vel. from 9" MP5 - 1093 fps.

    I like 147 gr. for nice shooting subsonics in the 9. I use WSF, but in your powder list, Unique should be very similar.

    Where did you get to crimp at .3775? With a plated bullet I do believe you are over crimping and destroying the plating on the bullet. I believe you will have better luck at .379. Pull a bullet and see if you can see a ring where the mouth of the case was. You just want no or just a faint line showing on the bullet..
  10. When I first began loading (about 5-6 months ago), I read about all the caveats relating to loading plated bullets and decided the best way to deal with them was to never load plated bullets. The MG (Montana Gold) are CMJ (Complete Metal Jacket).

    Before I fired my first reloaded round I pulled a few bullets to check for any excessive crimp mark and found no mark whatsoever.

    The bullets are a nominal .3555. Some wise person said to measure the bullet, measure the case thickness at the mouth X 2, add them together for the nominal crimp. That .3775 appears to (only) straighten the case, and of course it fits in a case gauge (and a big ol’ Glock chamber). It's also extremely accurate out to 75yds, which I understand I couldn't expect from a plated bullet where the plating was destroyed by the crimp.
