I can remember blowing the primer out of it's pocket with factory ammo on my then new 240 Weatherby Magnum, Mk. V. When I took the ammo back to the dealer, he took it and complained to the Weatherby rep. The rep told him, "if you don't like or ammo, don't shoot it." I was not given a refund or any more ammo. The rep wasn't interested in passing the bad ammo on to the factory.
I will not buy any ammo with the Weatherby headstamp to this day. E
