Rather than to buy a separate taper crimp die and add another step into the reloading process on my SS press.

Some don't crimp at all. Depends on what you are reloading and shooting it in.

I have yet to see a die manuf that does NOT have the ctimp ring built into the seating die. If you don't want to use it, back the die body out & just seat. If you want crimp; put a sized case in the press, run it up & screw the die body down until it touches, that is where the crimp starts. Screw it down another 1/4-1/2 tuirn & that is about all the tc you need.

Just use the existing seating die with the crimper built into it. Don't worry about what kind/what they like to call it. Remove the flare on pistol. Roll it in some on revolver.

What caliber? Auto pistol cartridge seating dies should have a taper crimp.(RCBS 357 Sig has a roll crimp though) Revolver cartridge dies should have a roll crimp. Redding started a revolver crimp that is claimed to be half way between a taper crimp and a roll crimp called a profile crimp in certain calibers. I think RCBS has more recently copied this for some newer dies in some calibers. Some offer a separate taper crimp die for revolver bullets that don't have cannelures for rolls crimps. I have heard that some Lee seating dies that are included in some die sets that include a Lee Factory Crimp Die may not have a crimp at all, but that's not the norm.

Most seating dies have a roll crimp built into them. Not a taper crimp. Exceptions do existt of course.

Only in revolver carts IME. Every die I have for any semiauto round has a taper crimp; RCBS, Lee, Dillon, Hornady.

Not talking about the crimp die. The seating dies have a roll crimp most the time.

Most revolver seating dies have a roll or profile crimp built in, most auto pistol seating dies have a taper crimp built in.
It would help to give the caliber you're concerned about.

The Horandy New Dimension dies I have for .380 ACP's are roll crimp. I called today and they don't offer a taper crimp for .380 ACP, nor will the 9mm/38cal taper die work for .380 ACP.

Actually, the tech I spoke to told me that all Horandy seater/crimp dies are roll crimp. They offer taper crimp dies for 8 calibers which do not seat, they are 38cal/9mm; 40SW/10mm; 400 Corbon; 45 ACP; 454 Casull; 460 SW; 475 Linebaugh; 500SW Mag.

Do you know this or are you just assuming. Because I have talked to Lee and Hornady and BOTH are roll crimp.

My RCBS 10mm/.40 dies have taper crimp. All my Redding revolver dies have profile crimp, in .38/.357 RCBS has both, RCBS Cowboy has roll, Hornady has roll, Lyman has roll, from Hornady's description for their 9mm dies-'The Seater Die features a roll crimp for most standard calibers, and a taper crimp for popular auto-loading pistol calibers.' not exactly worded clearly, evidently standard calibers = revolver calibers.
I guess we could go on and on, but I think most revolver dies have roll, and most auto pistol calibers have tapered is accurate.

RCBS makes the common Pistol calibers in a Taper/Seater and Roll/Seater. So you can get them either way.

What I think is funny is that the OP starts with a rather lazy question and we manage to turn that into a FCD vs no FCD and taper/roll crimp argument amongst ourselves.

IIRC, we have hashed these issues out a time or two.

I prefer to crimp directly in the chamber of the firearm... that way, you can be sure that the brass is EXACTLY the size it needs to be. Occasionally, it can be a bit difficult to get the slide to completely close, but that's why I keep a nice rubber mallet in my range bag.

That is stupid! The 380 does NOT roll crimp, why offer a die that doesn't work? Same for ANY of the semiauto rounds. I am glad I only have one set of Hornady & Lee dies then.

The integrated crimp in the standard 9mm Hornady seating die - roll, taper, bilaterally compressed. or whatever the heck it is - works just fine. There's no need to get a separate taper die UNLESS you specifically want to crimp in a separate station. I've made a lot of rounds using the single die, and they shot just as well as the ones made with separate dies.

Don't kill the messenger, I was :faint: myself.... Really regretful getting that dies set... I should have just used the bday credit I had and gotten RCBS ones.

I'm having issues with moly coated .380 ACP bullets that I'm evaluating. The Horandy set/crimp die I have is shaving lead/moly prior to final seating depth.

In actuality every roll crimp die taper crimps as the first, or beginning stage of the crimp. It is simply a matter of adjusting the die properly. It makes no difference if the die manufacturer says the die has a taper crimp or a roll crimp... you can taper crimp either way.

Conversely you can not apply a proper roll crimp with a taper crimp die.

Now, if you'll excuse me I have to go eat my Lean Cuisine and protein shake.

That's a shame about your eating habbits 'cause I made a nice pot of "gravy" from scratch with all the tomatos that got ripe on the same day and some meatballs made with veal, pork and beef. I even peeled the tomatos so as not to offend your deilicate taste. I was going to overnight it out to you but I'll just take it for lunch tomorrow.

You may never get the moly to work with a process of Seating and Crimping at the same time. Here is why. When you bend metal (which is the process of flaring and crimping) you have to bend the metal past the actual point that you want it to take it's final set at. So if you want "zero inward bend and also zero flare" you have to bend the metal inward towards the bullet. Then it will spring back a small amount and be at your "zero inward bend and also zero flare". This is not a issue when your just crimping. But if your seating and flaring then as your removing the flare you also moving the bullet. So the inward movement of the case will drag on the bullet as your at the final step of seating the bullet. Then the case spring back and has zero inward direction but it still was slightly inward while the bullet was being seated. Moly will tear easy.

I understand why, hence my reluctance to even try. I already ordered a Dillon taper crimp die.

I think Fred is referring to a 3 die set... that's the only way they used to come, seat/crimp in one die.
