I take it back, they were deprimed and sized, looks like. Pretty good looking stuff once I tumbled it for a while, the coloration from the factory annealing is still quite distinct, and there's no sign they were fired more than once, only one ejector ding on each, meaning they were shot through a Garand.
Chamfered the case mouths and primer pockets, checked for length and only needed to trim about 12 out of 100.
The necks are sized to 301 which seems sort of aggressive to me, so when I prime them, I will run a sizing ball in and out as well. That should kind of "tell" if the brass is cooked by mercury, if I get splits there or if they don't feel like annealed brass should when being sized. If they drive hard on the ball, but don't split, I'll stop short and anneal the cases, THEN re-size the necks.
