I've been shooting Lapua brass in a custom .308 win. So far I have reloaded the brass 11 times without any problem. I am using a set of Redding type S bushing FL dies. Primer pockets are still good and brass has only been trimmed a couple of times. At this point is it necessary to anneal the necks? Will I loose neck tension consistency if I don't? I've never annealed any brass before because I usually chuck it out before that became necessary. However, this .308 Lapua brass looks like it could keep going and going and going.
