    Hopefully my post is not a repeat. I’d like to reload 9mm for target practice. I am Not finding data and recipes for the following. (What I have to use) Remington SPP, 115g RN copper plated bullets from Xtreme Bullets and HP38 and W231 Powder. I’ve looked at several load charts and can not find anything using the above. Both powder manufactures don’t list anything using copper plated bullets or Remington primers And Xtreme bullets has very little low data for their projectiles. Just wondering if anybody could help me figure this out.
    Here is a quickload simulation to get you started:


    Code:
    Cartridge          : 9 mm Luger (SAAMI)
    Bullet             : .355, 115, RN Rainier 9mm
    Useable Case Capaci: 8.927 grain H2O = 0.580 cm³
    Cartridge O.A.L. L6: 1.125 inch = 28.58 mm
    Barrel Length      : 4.0 inch = 102.1 mm
    Powder             : Winchester 231
    
    Predicted data by increasing and decreasing the given charge,
    incremented in steps of 2.222% of nominal charge.
    CAUTION: Figures exceed maximum and minimum recommended loads !

          Enough that the bullet sets on the case and gets seated without getting turned sideways or shaving.
          No more than necessary.
          Different bullets necessitate different amounts of belling.
          A bullet with a flat base and a sharp corner needs more belling than a bevel base bullet.
