This thread has been very interesting reading. I have abut 100 Federal .308 cases that have been reloaded six or seven times and I haven't lost a case yet to separations, expanded primer pockets, or any other problem. But, I also have to admit that I only use the Federal cases to reload cast bullets with SR4759 powder. Since my velocities are in the 2,000 fps range, I imagine my pressures are below 30,000. That's probably why I have never had a problem with Federal brass. For jacketed bullets, I use strictly Winchester brass. The choice was purely by chance, when I started casting for my .308 a few years ago, at the same time I had picked up the Federal brass once fired at our range. Never knew there was a possible problem with it. Well, I guess I will stick to cast bullets only for my Federal brass and not cross over to jacketed bullets with it. A good thing to know about.
