You're reading a lot into my statement. Nowhere did I advocate running over-pressure loads.
It's a simple reality that there are presently only TWO brass manufacturers that will actually allow you to run most cartridges at their advertised capabilities. Alpha, and Lapua.
Just because the brass doesn't instantly crack in half, doesn't mean the brass can actually take the pressure... though I think it would be better if that would be the case since most people are using inferior brass and suffering the consequences, but they don't notice. Most people aren't trying to get very many firings out of their brass, so they don't even realize what is happening.
Good stuff here Greg- thanks!
