9mm taper crimp die

So setting up my reloader I was on the seating die and it roll crimps but read dont roll crimp but taper. So that means I have to buy another die for this.

What is a good die is the lee factory crimp good but will it also have bullet seat adjustment.

I doubt your 9mm seater die has a roll crimp cut, but in any case, even if it does, you can still use it to return your case mouth to straight from the belling. That is all you want to impart on a 9mm round with the crimp die anyway, just screw the body out until it just kisses the case mouth and straightens it, then adjust your seating stem to return the bullet seating depth to the desired setting.

If you do decide to get a separate crimp die (they are easier to setup than the combined seater/crimper die and do their crimping with the bullet not moving so there are advantages) get either a Redding taper crimp die or a Dillon. These two are the best.

Good luck, have fun.

Yea while messing around I got it to seat and close the mouth ahhh the joy of trial and error lol

My Hornady dies had the combined seating die and roll crimp. I picked up a Hornady taper crimp die from a buddy of mine for $15.

Glad you got yours set up.

You can do it in one operation, but a separate operation after seating is done is the best way as noted above.

I don't want to hijack the thread, but I have another question about taper crimping. I crimp my 9mm a few mils so the OD at the mouth is 0.380", just like the drawing in my reloading manual says. The cartridge might start at 0.383" and I end up crimping it down 3 mils. I set the crimp die by measuring the finished cartridge with a caliper. This weekend I wanted to see how much difference the crimping has on the seating of the cartridge so I took an uncrimped cartidge with an OD of 0.384" at the mouth and stuck it into the chamber of my pistol barrel. It didn't chamber all the way, as expected.


I ran the bullet through my taper crimper, the OD was 0.380" at the mouth, and it chambered all the way into the barrel.

I did this again with another cartridge, but adjusted the crimping die so it didn't crimp as much, 0.381" at the mouth, and the round still chambered all the way in the barrel, though a bit more snug, but it chambered completely. Now the question: if I adjust the crimping to give the minimum amount of crimp, just enough to get the cartridge to chamber in the barrel of this gun, and not crimping it down to the drawing spec of 0.380", would this present any problems? Has anyone here done it this way before?

I want to minimize the amount of crimp so I can reduce the chance of damaging the dry coating on the lead bullets I use, from Precision Bullets.
