What would the reasoning for that be?Generally they're okay to load. I haven't seen a case crimp that pronounced before. I've noticed that a lot of CBC handgun ammo tends to have crimps in the cases. I think the only precaution is to not seat the bullet below the crimp line.

Ok cool. I wasn’t sure if there was an explanation. Always looking to learn more.This is what I recall being recommended when I was learning to reload. That is, don't seat the bullet below the brass crimp groove. Not sure why, and since I haven't wanted to seat anything deeper I haven't challenged it yet.
I've loaded some of these. Magtech and Winchester (IIRC) have "cowboy" loads with these deep crimps. My problem is that I don't load lighter than 250 grain bullets in 45C, and usually I'm loading 300 grain bullets. I don't know of there is some trick, but I can't press these crimps out well enough with resizing and flaring, even with the RCBS cowboy dies. When I seat a bullet that pushes past this crimp in any way, even just touching it with the base, the case bulges out a little there. The Lee FCD won't fix it after the fact. I can chamber them in my Henry, but some of them fail to seat by a fraction of a mm in my Blackhawk, and then the cylinder won't rotate. I have to remove the cylinder and push them out. Once they've been fired a time or two at Ruger-only pressure, they're fine as wine, maybe just once is enough. I'm not sure. I think all the ones I've had trouble with in the Blackhawk were on their first reloading. Definitely the ones I've reloaded and shot twice are smoothed out.
The COL is fine. Some of the rounds chamber fine, others not. About half of the once-fired ones with the heavy rear crimp won’t drop into my cartridge gauge when they are reloaded the first time. They hang up where the case had the rear crimp. The crimp is stupid deep coming from the factory. No idea why they feared set-back so much more in these cartridges than in any others. Maybe something to do with using really soft lead?
I'm surprised the Lee FCD doesn't take care of this (it's about the only good use for one IMO).
