[Last Edit: Alderleet] [#9]

If its the repackaged black tip ap from SGammo, its corrosive.
The date debate about corrosive primers has been waging for decades. The 1952 cutoff of corrosive primer usage has been thrown around for a long time without anything substantive to actually back it up.
My personal take; anything govt made prior to vietnam should be treated as corrosive.
