I was looking through some of my old spent ammo when I cam across a 1916 DA case. I was wondering were it came from then remembered when I was a teenager my grandpa gave me a couple boxes of ammo too shoot when i just got a .303 rifle. so i looked back in all my cases and i found a bunch of DA 1916s and also a couple others. there two i am not sure. does anyone have the info on these? are they military? if i just put a modern FMJ bullet in them will they be okay or were they loaded with the fmj round nose ect?
any info please let me know.
