This will give a Pmax of 58,026 psi......the design Pmax for this cartridge/bullet/powder combination is 60,191 psi, so this IS a high pressure load, and definitely NOT a safe starting load.
I suggest you get a copy of Quickload and come to your own conclusions, bearing in mind that you have a potential pipe-bomb under your ear when shooting.
