My CVA Staghorn also has a size on the sabots you should use and I believe that is 300 grains. You're right on the edge of the table with some of those loads. So it would be interesting to learn just what kind of stress and barrel pressures a load like that is reaching.
Cayugad,
That load would easily yield pressures in excess of 45,000 psi. There is no doubt in my mind the pressure EXCEEDED 45,000 psi. Also, with the same powder charge and weight of bullet a .45yields pressures which are roughly 66% greater than a .50 cal.
