Hornady book max is most certainly book max, theres no sneaking it a little over like you can a lot of other cartridges where the data appears "conservative". Load up something at the hornady book max and you will certainly completely flatten the primer & wreck the brass.

Hornady brass is a bit inconsistent, some of it appears to be softer than the rest. At below book max load (even sometimes just shooting the factory ammo) you will get the odd bit of brass that stamps / hard bolt lift / ends up with a loose primer pocket. Out of 60 cases i have about 45 good cases now after a few reloads and throwing out what appear to be the soft ones.

Hornady talked about this in a couple of podcasts
Basically because there is less tolerance in the new designs and the rifles are chambered far more tighter then it brings book max to auctal max pressure.

Now i don't reload but it makes sense to me were as in the older cases had far more tolerance that the handloader could work in with that particular rifle before hitting pressure.
