An hour at 350 degrees ... that may or may not have softened them .
Annealing is only done to the neck - shoulder area ... not the complete total case .
I would at least do a crush test on the body of one or two to see if they were softer than an un-baked case . You don't want any head seperations when firing these .
30-06 are just too common and easily available to run the risk that the whole case , including primer pocket , has become too soft .
I'm not the brightest bulb on the tree but I wouldn't risk shooting them ...
