I'm kinda favored to RCBS. I guess that's just how I feel about it. I think if you take a reasonble amount of care and check your fired brass, trim it regularly and watch your primer pockets with max load or close loadings you should experience 5 or more loadings per case. I personally toss 'em at 5. Some keep on. I once decided to see how many deer I could kill with a single casing. It stopped at 9, with a blowthru at the top of the web. I don't reccomend doing that.
I also reccomend setting your dies to your individual chamber/gun. You may get some more neck/shoulder life if you are experiencing some neck splitting by annealing. I think this is what bc was getting to..... but I sure don't want to speak for him....
