Recently, a friend gave me some old ammo and I have 2 questions about it: #1 Is it safe to use? #2 Would it have any value for a collector? Description: A. Winchester Western WWX 50 Center Fire Pistol-Revolver Cartridge. X380AP, 380 Automatic, 95gr Full Metal Case, 50 Pistol-Revolver Cartridges. B. Made by Olin Corp, Winchester-Western Division, New Haven, CT. 06511 East Alton, IL. 62024. C. Cartridges are packed loose in a white box and, someone wrote the date, 5/10/84, on outside of box Does any one have any insight about this, thanks.
