FYI - Prior to writing a column for Shooting Times, Allan Jones worked for Speer and worked on several editions of the Speer reloading manual. Much of his writing is based on results of lab testing at Speer.Hmm, I guess I'll have to add this guy Allan Jones to the list of gun writers of the like of Chuck Hawks, and take what they say with a grain of salt. Hate to say it, but for once in my life I agree with something T. O'Heir wrote.

Do you mean mechanical hardness or requiring more energy to ignite? A lot of shooters mean the latter, but Jones was talking about the former.
When talking about the hardness of primers, it is commonly assumed to be the hardness to ignite
Commonly? Maybe for you. For me it has always been the opposite. As in hard cups to prevent slamfires in military rifles with floating firing pins.
