Do any of you folks collect cartridges?
I ran across one a little while back that kind of stumped me for a while!
It has a Lake City headstamp with a 67 date but it was less than an inch
long. and bottlenecked. after some careful measuring I came to the conclusion that you can make Japanese 7mm "Baby" Nambu cartridges
from .30 U.S. Carbine cases! Someone did a fine job of it also!
Collecting cartridges is a real interesting hobbie, You all should try it!
