Hi, I had a question I thought some of you gun folks might be able to answer for me. I found an empty cartridge in my backyard which I assume is a bullet cartridge, brass, with headstamp WRA (Winchester Repeating Arms) and the number 45 beneath it. Does the 45 refer to the weapon or the year of manufacture? It is placed like the year of manufacture and all it has is 45, nothing about type of gun.
Cartridge is about 1 5/16 inches if that helps.
