The Herter's 16g gauge shells wear the CIP license/logo/label whatever it is.
16 is the only gauge I have left, but I seem to remember that the 12 gauge Herter's were also Loaded to CIP standards.
Viewing the initial pictures of the failed LC Smith, my confidence in the Herter's shells is unshaken.
There is a lot of variation in the steel head shells.
The heads will all fall within the dimensions published by SAAMI or CIP as the case may be, but if you put a micrometer to them you will note that the euro made shells have on average a smaller diameter head and thinner rim than US made shells.
Remington Gun Club in 12 gauge is right at SAAMI maximum diameter, at least the last ones I measured were.
