New to reloading, need some help
I am completely new to reloading, I have just purchased a Hornady LNL AP press. I had planned on Hornady dies but they are several months behind. I can find available Redding sets but I am confused by the difference in the two sets.
Below are the descriptions of the two sets in question. The question I have is why there is no expander die in one set while the other has it. I thought the expander die was to open the case after the resize so the projectile can be placed in the case. Also any comments on personal experience with these dies would be helpfull. Just reloading .44MAG at this point.
Redding Pro Series Die Set, 44 Spl/44 Mag
Pro Series Pistol Die Sets are designed for use in progressive reloading machines. The expander die is eliminated from the set and a separate crimp die is substituted. The set includes a carbide sizing die, bullet seater (no crimp type), and a separate crimp die.
Redding Titanium Carbide Die Set, 44 Spl/44 Mag
Titanium Carbide Die Set includes the carbide sizing die, expander die, and the bullet seating die with built-in crimp ring. Use these sets in a single stage press.
