I just wanted to comment on the "charts and graphs" that somebody mentioned being shown here. There has only been one, showing a .30-06 with a 150-grain bullet and Varget. It is not anywhere near a maxiumum load, in fact the peak of any of the curves is around 44,000 psi, which is far below the peak (and most efficient) pressure for Varget, or many other modern rifle powders.

The pressure curve at 55,000-60,000 psi with most modern rifle powders shows a much steeper climb to the peak, and a steeper drop-off. I have looked at a bunch of Pressure Trace curves and at 55,000 to 60,000 psi the curve has a much more obvious peak.

So the "charts and graphs" are not plural, and the single one shown does not represent a typical load for modern bolt-action rifles.
