Military match ball ammo question

I bought a 1000 round can from a club member of FC 71 match ball ammo, lot fc-1-7, for a whistle. Any experiences with the 1971 stuff? Does it actually shoot better than the current bulk ball ammo? I intend to use it only on the long line for now and use wimpier handloads for the shortline.

testing it in your gun is the only way to tell for sure but most of the old ball military match was good stuff.,
