LRF,
I didn't have a 30 Herret but did have a 357 Herret. They both work much better if the sizing die is set to "kiss" the shoulder and not set it back. Early complaints of case head separations were traced back to setting the die, so the rim bumped it hard. Case life with the properly set dies for my 357 was good. I started setting all my dies that way and am very satisfied with my overall case life. Bob Mileck(?) wrote a lot about the cartridge and I think he did a lot of the development. It is a pistol cartridge, but since it was used in Contenders it was loaded very much like a rifle cartridge.
