I just inspected my once fired brass a little more closely for my 8mm Mauser reloads. I made 5 rounds each of 46.0, 46.5, and 47.0 gr H4895 an a 150gr Sierra SP (Hodgdon lists 50.0gr as max). The firing pin dent looks normal and the primers weren't flattened, but on closer inspection, it the primers are 'pushed out'. It looks like the primer came out of the pocket just a little on all the rounds, as if they weren't seated fully.
Is this a sign of overpressure? I'm pretty far under max, so I didn't expect to be overpressure with the loads. I've fired quite a few rounds of Turkish 8mm surplus in that rifle, and unfortunately, I don't have any of those once fired cases around to see if the primer pushed out of those too.
