Published maximum loads in manuals are not the realm of lawyers, they are the product of ballisticians discovering maximums due to pressure checking or actual case observations in actual guns.
SAAMI maximums, but no less real.
When I 'push' I at least understand the ramifications, and that I am totally responsible for my actions.
When another handloader decides to 'push' I hope it is also done with a full understanding of the ramifications.
My guns are different than everyone elses, and I never-ever-ever forget that.
Safety first.
And yes, screw SAAMI (.....
still echoing.....)
