I have some Lapua Palma .308 that is overr 20 years old, lost count on how many times it has been loaded. At a guess I would say close to if not more than 50. I ran them hot and lost about 6 due to loose primer pockets. Never split a neck or had any seperations though. Depends on the manufacturer, how they are sized, how hot you are running, if they are annealed properly etc. 
Get a primer pocket testing tool and a bent paperclip for internal exams and a lighted magnifying glass.
