Where can I find roll crimp dies for 9mm and 10mm and 45ACP and 45 win mag?

Your advice would be most appreciated. I’m shooting revolvers using MOON CLIPS: S&W 929, S&W 610 and Ruger Redhawk 45Colt/ACP. ICORE, IPSC, IDPA. A Taper crimp is normal for pistol cartridges but when used in a revolver with a moon clip the case heads frequently catch on the mouth of the cylinder. A roll crimp would prevent this. Very difficult to find. Thanks Brian

You can get the 45 ACP did from RCBS.
Roll Crimp Seater Die - Group B - Popular Pistol Cartridges | RCBS

I'm sure if you look on all the did manufacturers sites you will find what you are looking for.

Redding Profile Crimp dies might work too.

I find that if I set my Lee taper crimp dies down far enough, they will roll crimp.

Die sets used to come that way

Hey Brian, You are correct in wanting to roll crimp for revolvers, but you shouldn't have to search for special crimping dies. Back in the 80s I began to reload for both 45ACP and 380Auto. I bot RCBS three die sets for both cartridges and the were furnished with roll crimp seater dies as standard. If you wanted to taper crimp, you had to buy a fourth "Taper Crimp Die" and set your seater die not to crimp. That said, I would just search auction sites for a vintage set of those dies and get the roll crimper as a bonus!

A little more taper crimp might help.

Do your bullets have a crimp groove? If you’re planning on using a roll crimp you’ll need to seat the bullet based upon the location of the crimp groove. Trying to do a moderate to heavy roll crimp without a crimp groove will result in deformed brass. Using a light roll crimp is pretty much the same as a taper crimp.

I can't think of a 9/10mm or a typical 45 ACP FMJ that has a cannelure for crimping - I could be wrong but . . .

Lee .45 acp dies will roll crimp if you run them down tight enough..............

Both my old 9mm and 45 acp RCBS dies are roll crimp.

Not dead sure but I think a .38 S&W roll crimp die would work for the 9mm.
