I have not done that. Based of the 9.3x62, I'd guess a 250 grain bullet at 2500 fps would be possible.

In a 9.3x57 Husqvarna M146 ( 'C' ring
FN M98 action), I've worked up to 2433 FPS with 250 gr TSX at 100% load density of H4895 in necked up and fire-formed 8mm Prvi Partizan brass. CCI 200 primers look normal and cases extract easily. Don' have any idea what the PSI are running but the results, so far, suggests that your guess is a good one.
