Not sure where to post, but I have a few questions. At a local shop, there are approximately 100 loaded rounds that are what would appear to be well over 40 years old. They are cupro-nickel bullets, the brass case itself for the better part of 90% of them appear to be very good. I know it is not Kynoch or Eley. My questions are what are some of the other makers of this ammo, and what would one consider a fair purchase. One the case head, it reads just .350 Rigby Magnum. The store is asking 4.00/round
