O.K., if you're loading for a bolt gun and all of your brass is either new or has only been fired from the rifle you are reloading for, I'd get a neck sizing die. Works the brass much less and since the round now fits the chamber it was fired in, you'll usually get more accurate ammunition.
I guess the reason I need an RCBS crimp die is my friend with the loading system says they work better for precision ammo then the standard dillion crimp that comes with the set.
I've been wrong before, but I don't see a crimp only die offered by RCBS. I know they sometimes make special dies exclusively for different companies as I have a 45/70 taper crimp die I use for my Sharps that was made for
Dixie Gun Works. I still believe that there is no better crimping die than the Lee Factory Crimp Die.
As far as prices on Dillon equipment, Dillon doesn't have many authorized retailers and most that I've found on the net are selling for exactly the same price as Dillon themselves. If it's the same price, I'm buying straight from the manufacturer.
Also, if you're trying to load precision ammo for a bolt gun, a progressive press isn't always the best choice. Not that it can't be done, but it will limit your powder choices as some types of powder don't like to feed through a powder dispenser plus using a progressive press eliminates your ability to use some specialty dies like the
RCBS Competition Seating Die.
