The only rifle I have shot the .308 SP brass in is a Winchester Model 70 bolt action, and then, only with low node loadings, but I've never noticed anything strange about the primers after firing. What you're saying makes sense, though, and I'll start watching more carefully.On the 308W SP brass you will blank the primer if you don't have the bolt head bushed and the smaller pin fit to it. Especially bad in an AR10. But at the same time, it is not a bad thing to have your bolt bushed and a pin fit to it. Also the firing pin springs need to be changed at regular intervals also. Or you will start to see large SD variations. And primer flow even though the bolt has been bushed. The pins need to be strong enough to resist being push back into the bolt.
