Where was the W located on the projectile? I'm assuming it would be on the base and would be willing to pull one down for the sake of history and science! :) Scouring through other forums, cartridges of the world volumes, and auctions the "8-30" on the bottom right of the top label definitely indicates month and year of manufacture. Just as reincarnated stated I was expecting a headstamp bearing WRA Co. and was surprised to just see WRA. The 30 on the cartridge from all of my research also is a year of manufacture so the box and cases are at least from the same year but who knows if they actually belong together. I would certainly love to know. Pulling a bullet and posting pics of the bullet and powder may help?
