Crimping without a cannelure?

A light roll crimps works fine for these bullets between 800FPS-1200 FPS. Just don't put a full charge of H110 behind them.
Dead soft lead + thin plating + no cannelure make these bullets kinda suck for seating/crimping in the same step. One of the reasons I don't like loading these bullets on my SS press.

A better answer to some of those crimp difficulties
Check this out and give these a try:

there aren't that many calibers available, but of the one's he offers (and this is the ONLY place to get these), they work exactly as expected.
When I first found out about FCDs, I soon wondered why I wasn't getting collet style dies when I ordered so many of the calibers that were available.
I would bet that the collet style are much more expensive to produce when that type isn't indicated, as on the bottle-necked rifle calibers.
And there is always the possibility that they could be a little bit tougher to use effectively.
I have found myself totally satisfied with the calibers that I can now collet crimp rather than those fall-back to the roll -or- taper crimping methods.
As far as I'm concerned, this is a great alternative for those calibers where available.

This thing looks different than the roll crimp Factory Crimp Dies, is it just a hoax, or something made to look a little better than it is? Or is it completely different than a roll and a taper crimp from a Lee FCD? Thanks, I will definitely look into those, if they are different.
No hoax.
They are custom made by Lee for the RanchDog.
I found a .45 .70 collet style FCD before I ever came across these.
A straight wall collet crimp die had exceptional use for me, so when I found the .357 Magnum and .45 Colt through RanchDog, I ordered them the same day.

Lee took the collet style crimp die concept that they use for rifle calibers and made collet style pistol crimp dies.
The collet style crimp is an excellent concept and I would think these collet style pistol crimp dies would work well with plated bullets.
For bullets with a good cannelure or crimp groove, I would prefer the old fashioned roll crimp, but one factor these collet crimp dies have going for them is that case length would not affect the crimp. You could not buckle a case with these, unlike normal taper or roll crimp dies.
I use a roll crimp die for plated bullets in .357 but adjust it to give a light crimp. Hoping to buy a dedicated taper crimp die for my light .357 loads. In recovered bullets I've seen the crimp line (crease) in the side of the bullet, but no peeling, leading or any other issues.
I shoot the .357" 148 DEWC a lot in .357 and a light crimp has alway been enough up to 900 fps.
The FCD die has a very abrupt crimp area that makes light crimps hard to maintain because of minor variations in case length. I don't need that or the resizing of a completed cartridge, so my FCD die has become a spider's nest.
