At the last three gun shows - in the past three weeks - I haven't found any guns, but I scored a number of rounds for my abbreviated cartridge collection.
Eleven rounds of 8x50mm Lebel ammunition; three were recent manufacture PPU rounds, four were fired and reassembled cases with early projectiles and several (I'm not looking at them right now) were cupro-nickel jacketed, French head stamped rounds with the annular ring for use in the Kropatschek magazine of the M1886 Lebel rifle.
A large number of .25 ACP rounds, many with cupro-nickel jackets. I do not have a count, but I have several "C. C. Co" head stamps with old type jackets, and a few Norma versions of the .25 ACP.
That will keep me busy for a few days, sorting and identifying all of them.
