Just bought a set of 44 Mag Hornady New Dimention dies and I am running into an issue. If I load FMJ's the seating die seats and crimps like a champ. If I am reloading lead bullets it pushes them past the crimping shoulder even if I remove the seating stem. You can actually see where the crimping collet is contacting the bullet and forcing it into the case. This is causing the bullet to be seated deeper than needed and crimping it above the bullets crimping shoulder.
Anyone else run into this problem? |

You can avoid this headache by separating the seating and crimping operations in separate dies. 
Cheapest way is to add a Lee FCD, factory crimp die. When you seat and crimp in the same operation, case length is critical, as you found out. Good luck. |

on a single stage press you can use the seating/crimping die in one pass for seating, then just for crimping the next pass. For progressive you'll need that 4th separate die, but I think the OP would want to use a roll crimp vs a taper crimp for 44 mag. It looks like the Lee Carbide Factory Crimp Die roll crimps for revolver rounds, is that true? http://www.leeprecision.com/html/catalog/dies-crimp.html |

Mighty Assaultrifler you have provided me with lots of insights over the years, for that I thank you. So guys after reading your posts the first thing I did is hit the Midway sight, and found this. Midway Sight Looks like it uses a roll crimp after all. |
