CAREFUL!
The online Hodgdon data is not in PSI but in CUP! PSI and CUP are 2 different animals
You have a little room, but not as much as you think! MAX is going to be in the 57-58gr range with H4831, at about 2850fps give or take. Only the slower powders such as R-22, H1000, IMR7828 will give you 2900+ safely with 160s. Not to mention you're running a 22" bbl as well. 2900-2950fps with 160s will be top end!
