Bought a new collection with a lot of odd stuff…
Has anyone got info on a .50 BMG HV.
Apparently a .50 BMG bullet in a ?? 60mm exp. case.??
Bullet is copper with no coloring on tip.
Looks like regular .50 ball bullet.
Note with cartridge says marked barrel erosion.
Franklin Institute in PA
Second question is a W.C.C. cartridge.
Belted magnum HS W.C.C. and 60 No other marks. .30 cal.
