Wanted: .50 BMG (12.7x99)

Looking for collectible .50 BMG cartridges

Looking for experimental/rare 50 bmg cartridges. Some that i’m trying to find are salvo squeeze bore type 1, 3B, 5, and 8. Frangible Armor Piercing (FAP) round, and a lot of foreign rounds.
If you are interested in selling please PM me a price and photo. As long as I don’t already have one of those round in my collection i’m interested.

Thanks, Luke
