Oh my goodness...the first can I bought is some ancient stuff:
WWII type packaging
1948 Frunze/#60 Type L light ball on stripper clips in 15 round boxes. 20 boxes/60 clips/300 rounds per tin, 2 tins per wooden crate. Galvanized tin soldered closed with pull tab.
I have no reason to believe that it won't shoot fine. The tin is still sealed as far as I can tell.
That's not what's in that can.
You have 1973 production Novosibirsk-made "LPS" light-ball mild steel core in bimetallic cases using powder from 1972, so it was likely made early in the year.
Galvanized cases with a pull tab look much different than the tuna cans like this that require a tool to open them.
