Hummer70 has one 308 case that has been reloaded 158 times, IIRC. Certainly, if the reason you are losing cases is neck splitting, then yes, it will extend life.

I will point out that when I put that chart together that MG posted from data in a metallurgy book, I was not cognizant of the fact the percent cold working of the brass being annealed would affect it. That chart is for one hour, and I can probably deduce what it was from that. Meanwhile, please take a look at my second post in the Annealing White Paper thread for a taste of the complexity of the situation.
