Loaded some 308s,some in military brass and some in commercial brass.The military brass has flattened primers after firing but the commercial does not.Too hot?
If every other variable is the same for both sets of cases then I would say that the military cases had less capacity and therefore the pressure was higher, flattening the primers. That's the usual reason because the military cases are thicker to begin with. If you switched variables between sets of commercial and military cases then you have to tell us what you did in more detail.
There is also the possibility of other reasons that have to do with chamber wall grip and a couple of other factors but it is most likely that the military cases have a smaller capacity.
