    My experience with 458 socom was only with jacketed bullets, but I couldn’t get the powder through expander to open the mouths enough to seat properly and still pass a chamber gauge. I had to use a universal expander and bell only the mouth, then straighten it back up with a factory crimp die.

    I don’t know how much of a difference this makes with cast though.

    This is my first experience with the powder through expander. It does flare the case if you adjust it almost all the way down. I may see if I can take it apart and see what size the button is before the flare.
    I also have the universal expander but haven't tried it on the 458socom cases.
