We have pulled bullets and tried to make 22 rim fires fire OOB and can't make it happen in a well made firearm.
Overcharges simply blow the case, sometimes damage the firearm.
Some cartridges detonate, in my experience these are very loud, produce much black smoke that blows out of the action, depending on the firearm some out of the trigger, sends extractors flying, damages actions and barrels. I feel these are double charges or more of priming compound.
Mistakes are going to happen both in the firearms and in the ammunition, I just hate to see the firearms makers take the mistakes of the ammunition folks on the chin.

I believe there is merit in your theory as to a "hot" load blowing back the bolt before the bullet leaves the barrel which could cause the case to eject prematurely and explode. My Victory amazed me the other day by auto-cycling CCI 710 fps Quiets. It wasn't a fluke either, multiple magazines with and without suppressor installed. First auto 22 I have ever shot that would do this without considerable work to lighten the bolt and springs. S&W might want to look at the factory spring and make it a tad heavier, although i really like it.
