I'm getting set up to load 38 Special/357 Mag pistol ammo and have some questions. I will be loading cast bullets from two Lyman moulds - one with gas checks and one without.

1) Do I need a 3 die or 4 die set?

2) If shooting these bullets in a Ruger Blackhawk do I need to crimp the bullets? If so, roll crimp or taper crimp?

Thanks,
George

GKing,

I have reloaded every 38/357 Magnum round I have ever shot with a 3-die set...Carbide for sure. That includes cast as well as jacketed. And I do put a slight roll crimp on my cartridges if I am using a fast burner. More crimp if I am using a slow burner and it produces heavier recoil. Good-luck...BCB

In the case of Lee dies, you will see the following:

3 Die set:

• Sizing die
  Flare die
  Seating/Crimp die[/list:u]
  
  4 Die set:
  
  • Sizing Die
    Flare Die
    Seating Die (may or may not have crimp, I've never checked)
    Crimp die[/list:u]
    
    I've used 3 die sets for .357 Magnum, they work fine. In .45 Long Colt and 9mm, I have 4 die sets. I really like the crimp die supplied in these better than the crimp built into the seating dies.

i've loaded plenty of 357's, cast and jacketed. using the lee bullet seater and crimp die combination. very little trouble with bullets backing out. might be a different story with the larger calibers.
