Herter's shells do indeed carry the CIP logo. However, that only means that they meet CIP service pressure standards. For "standard proof" loads, that figure translates to 10,730 psi as measured by transducers. Not all that different from SAAMI's 11,500 psi service pressure standard. Chances are, most CIP loads are going to be well below that, and that'd be particularly likely in the case of a 1060 fps load.
