    I have a Lee Sizing Die in .355". Could I successfully size a jacketed 357 Magnum bullet though it with some lube?
     
  2. COULD you? Probably... but I wouldn't recommend it.

    I regularly resize .312 jacketed bullets down to .309 for my .30 cal Lugers so I don't think you'd have any problems.

    Most 9mm guns will run a 0.357" jacketed bullet just fine. Just something to consider.

    So...If the gun will shoot them, I guess its safe to say that I can size them down easily?

    I don't know, I never bothered. you're the one with the sizer and the bullets, why don't you tell us?

    I have shot .356 bullets (38 super bullets) in a 9 mm with zero real difference over the chrono and in the gun.

    Yes you can, but you need a good lube like Imperial sizing wax. I routinely size down 0.429" 44mags to shoot in my 404 jeffery's 0.423 bore. The 300gr bullets go thru a two step process; 0.427 die first & then the 0.423 die. They shoot pretty well, usually under 1 1/2" @ 100yds, plenty accurate to practice snap shooting @ 50yds & waaaaay cheaper than any 404 bullet available.
    FWIW, as noted, shooting an oversized jacketed bullet can be done in the 9mm or 357sig for that matter, but you can't just plug & play, you need to work the loads up.
