This one?
Warning: The above graph depicts 150 grain volumetric loading pressure traces measured under laboratory conditions via radial transducers. These loadings that MAY be in excess of manufacturer's recommendations. The highest pressure load combinations depicted here are recommended and touted by many: Knight Rifles, Hornady, Thompson, and others. I obviously do not suggest their use, for equally obvious reasons.
