Deep in the bowels of you life insurance policy somewhere around page 18, paragraph 3, section C, it states "sky diving and not separating your brass", are reasons for cancellation. But hey...other than that I don't see a reason to kept track of number of firings. Your brass will tell you when it's had enough, usually splits in the case mouth during the flaring stage show first. Do visually check about a quarter of the way up from the base for signs of 'ringing'. That is usually a sign incipient case separation is in your future. You can check the inside of the case with a bent paper clip for severity.

Thanks for the "ringing" tip. I haven't read much if anything on that. Can I check the ringing in my ears with a paperclip too?

That's Funny.....try a tuning fork so you get the ringing at the right pitch.
