Not sure I would want to tote a 25 pounder all day, even with it in an African/MG carry position. I know I can do 17 pounds, but 25 seems a tad too much.
Not knowing what powders or COL are exactly for your loads, and using a 26" barrel my internal ballistics program predicted a peak chamber pressure of ~ 43 ksi for your 730gr load and ~ 38 ksi for your 3/4 oz load. I was using Rel 22 for powder. Regardless, still very impressive ballistics with mild pressure.
The hotter loads you mentioned someone else getting ran 58 ksi and 59 ksi respectively.
