Case life with the Grendel is incredible! I routinely get more than ten loads from the cartridge and the failures are not neck splits. Others have reported even better case life.
Further, there is no accuracy advantage to the 0.295 neck. The compound throat gives much tighter lateral clearances than any neck that can safely release the bullet can offer.
Follow the discussions about accuracy with the Grendel and you will see that the cartridge, even in what many still think os the "sloppy" AR, is excellent with many reporting 0.4 moa and smaller groups. If one is lucky, a bolt gun might equal or better this accuracy, but the chamber will not the factor that causes the improvement.
When you share your case life are talking in a AR rifle or bolt action? Where do you generally experience case failures? Do you anneal your brass and if so at what round count do you strive for?
