I like them. A lot. But my favorites I have to cast myself.
The Ideal/Lyman 358432 is designed to seat out of the case. At 159gr as cast you can just load them the same as you do a SWC. I use 4.0gr of W231 which is the same thing I load in the SWC.
Then there's the Lee 410-208-WC, a .41 magnum full wadcutter which in the .41 Magnum you can load hotter than you'd probably care to shoot.
Here's the 358432 next to a standard 150gr SWC:
This is an as cast 358432 with a .41 wadcutter on either side:
