I push my 150 gr Speer SPBT with 59 gr of H4350. My old Hodgdon manual lists a a velocity of 2968 with a 165 gr Sierra SPBT. I just checked the Hodgdon website and the loads they list for H4350 are a bit lighter. Don't know what to tell you. My loads do not show any high pressure signs, but you may want to start a bit lower and work up.
