I'm not sure what a profile crimp is, but what you want is a roll crimp for revolver rounds.

Looks like a fancy marketing term to me. The description desribes it as a roll crimp. It will work fine to answer your question. Any 357 mag crimp die will put a roll crimp on your round, so you don't have to worry about buying the wrong one. Redding make really nice dies, so if you want spend the money I'm sure you'll be happy.

I have always roll crimped for heavy revolver loads as thats what I was taught way back when. I roll old school single stage for my rimmed pistol stuff and am not willing to change anything sometimes once I get the lock-rings on my dies set where I want them LOL. I guess I'm illogically cheap too sometimes

But yeah, if you are starting fresh with this caliber, profile crimp is not a bad thing.

I always dedicate a die for crimp instead of crimping with the seater die so as long as you are getting an extra die anyway you can go this route easily.

I roll crimp hot(296), jacketed rounds, taper crimp low power lead stuff.

Yes, you want a roll crimp for .357, but for a beginner I would advise against buying a dedicated crimp die unless you are certain you need it. The most common course of action would be to buy a carbide 3 die set, which will include seating and crimp in one die. Get used to that and feel your way around, a specialized die like that isn't really necessary unless you intend to seat and crimp in different stages.

I used to reset the seating die (back out seater) to do the roll crimp separately because I have never liked the idea of crimping while the bullet is still getting pushed down. Then a friend gave me some extra pistol die sets so I scarfed the seating dies and turned them into dedicated crimp dies for my rimmed pistol loads.

Just seems better to crimp as a separate step. I will admit that I did crimp while seating way back when I first started loading.
