The point of the article was for the recorded thicknesses. I agree construction varies, and so can hardness. Which is precisely why the mil-spec for sensitivity revolves around the anvil height, not what metal is used, or how thick they are.

There was a hardness test done over on sassnet.com this past January, for those interested.

If someone wants safety for a floating firing pin, buy a primer built with that in mind. Who owns who, who uses what for parts, changes. Remember the complaints(20+years now) about Winchester primers being "too hard"? Well they are still "hard", and thick. Sensitivity is what changed, via the priming mix/anvil height. Hard, or thick isn't what you should hang your hat on.
