Thank you.

Virtually no data out there on a modern gun and 7.5 Swiss load.

I am working from down low quite a ways. This one was a pretty sudden cam over in regards to serious bolt lift (interesting the primer was pretty good and no smear on the case head)

The thought was that a modern gun should be able to take a 30-06 pressure.

Not sure whats at play if the shorter and fatter case really is a lot more efficient or?

It won't change my approach (start at K31 load levels and work up) but it has my curiosity tweaked.

I will do a test run of H4350 and see how that goes.
