Just for fun, I plugged an 835-grain .729 conical and a 545-grain .715 round ball into the fpe calculator at beartoothbullets.com and got these results:
For 4,008 fpe, you need to get the conical moving 1,470 fps, and 1,275 fps for 3,015 foot pounds.
To achieve 2,984 fpe with the round ball, it must be going 1,570 fps; 1,290 fps would yield 2,014 fpe.
Don't know if the higher velocities are achievable safely in the short-barreled Kodiak .72, but with Swiss, maybe.
