Die 1- resizes brass, has decapping pin. set die in press to resize case, and remove primer. Doesn't make any difference mag or spl, in this step.
Die 2- Flares brass. NO DECAPPER IN THIS DIE. Set die in press, and adjust the flaring bell, so that it just flares the case mouth. Flaring bell will need to be lower for spl, than for mag, as spl is shorter. If you are using Lee dies, the flaring bell is probably hollow, as folk using a progressive, like to put powder in the case at this step.
Die 3- seats bullet, and crimps case. Sit the bullet in the case, and adjust the seater to proper cartridge length. Once length is set, back of seater, and crank down the die as a whole, to set proper crimp. Then with cartridge still up in die, crank back down the seating stem. This will seat and crimp in one step. Alternately, you could do these steps separately, crimping with the same die, or with a Lee factory crimp die.
Of course before seating a bullet, you'll be priming and putting powder in the case. I'm as confused as the rest of the responders, H4831 said it sounds like you are trying to flare the cases, in the sizing die. I agree, reading your post, that is how it sounds. Maybe try and type out your loading process, don't leave out any steps, seems like something is not getting done properly, or you are attempting to do something with the improper piece of equipment for the job.
Decapping pin- little skinny pin, in the sizing die, pokes out primer
Flaring bell- fat round thing in die 2, flares case for bullet seating
Flash hole- tiny hole in cartridge case, primer flash goes through, to ignite powder
If the brass is flared enough to seat the bullet, that's all you need. The less flaring, the longer your cases will last.
