I've used Lee, RCBS, Redding, Herter's. I use the Lee in my Loadmaster progressive work just fine. Redding are nicest, but cartridges produced from Lee or Redding both function the same. A carbide sizer is pretty much standard since Lee brought price down 30 plus years ago. I seat and crimp separately, with a very light crimp with a standard die or a taper crimp die. I do not use the Lee 'Factory Crimp Die' for the 45 ACP, it does get mixed reviews. Lee's neck expander that allows powder to charge the case while expanding works well for me. No real tricks to 45 ACP, setting bullet seating depth/cartridge overall length to work in YOUR pistol is probably the most important step.
