    Muzzle 10' from 1st screen, Glock 32 with 4" barrel.

    Speer Gold Dot, #23918: av. velocity 1355, SD 5.3.

    Speer Lawman TMJ, #53919: av. velocity 1305, SD 3.

    Winchester whitebox FMJ, #Q4309: av. velocity 1339, SD 13.

    Have that apparently hot-loaded Fiocchi 124 XTP load on the way and will be reloading a bunch; will post more later.

    Corrected the Lawman data.
     

  3. Great post. Looking forward to more.

    I think someone could make a killing selling 357SIG loaded to the max 1450-1500fps. Right now, all the ammo makers are greatly under loading it.

    TY.

    According to all the reloading sources I can find and which I summarized on that Excel spreadsheet I've 'advertised' elsewhere, it's gonna take about 50000PSI pressures or 7" barrels to get to 1500FPS with 125g. bullets. My list contains over 50 maximum loads; the highest velocity is 1438FPS.
     
  5. Can you send me the spreadsheet?

    I'm certainly able (and willing) to but only if I have your e-mail address.
     
  7. Thanks!
     
  8. DoubleTap boasts of those speeds, but recently I have come to question if they haven't been loading deep cavity GoldDot 124 grain bullets intended for 9mm into their line of 357 Sig rounds tha should be loaded with the shallow cavity high velocity 125 grain bullets. I'm usually not one to nit pick, but if performence suffers as a result I don't want to die because of it, if faced with a life or death shooting.
