My 308W Lapua cases have done me for about 5 years now but I had one split a neck yesterday at the range and am figuring that they are probably nearing the end of their life. The way I see it is if one has split a neck then the others will not be too far behind and I don't think they owe me anything. I don't have a detailed record but guess some must be near to 20 firings while others probably only have a few firings on them.
I have 100 new Lapua cases sitting ready to go and as I don't have any clear idea of which of the old cases have loads of firings and which have a few I've decided to replace the lot over the next while.
In real world practical terms is it necessary to reduce the load and work back up with the new batch of cases or is it sufficient to load a few to my standard load and fire them checking carefully for signs of pressure? I really, really don't want to have to play at working up loads again if I can avoid it.
