The sizer needs to be slick or the boolit will stick. I wish there were .433-434 dies available. I'd be happy with a four cavity mold that dropped .433 so I could pan lube without sizing. I have a mold that drops .436 and have to size .432. My gun has .433 throats. I could powder coat but I'm too old to start over.
