Some of this is good stuff. Other lots are dangerous as the cases split when fired. I saw some of the bad stuff on the Brandon,MB rifle range some yrs ago along with the boxes with lot numbers shown. The old Culver's Shooting Page used to keep a database of the bad/suspect lots.
I fired some of the good lots thru a friend's Garand down in Arizona and found it quite accurate. I'd treat it as having corrosive priming.
