Running that back, 1,000ft.lbs. with a 150 means an impact velocity of 1732fps, so basically the same ~1800fps floor I mentioned above for the 180grn 35cal HorCor. I don’t love the expansion at 1800, but it’s one of the better 35 cal pills for that speed. Looks like it solves the OP’s problem, however, for the range he needs to harvest game.
