Why? I've had case head separations in .357 Magnum when I was loading over 40Kpsi, but in a revolver they are more of a nuisance than anything else. I inspect my revolver brass for cracks at the case mouth, but that's about it. I keep reloading it until it fails.
OTOH, I wouldn't want a head to blow off in a rifle or a semiauto. I'm rather attached to my eyes and fingers.
