My ears have not noticed little difference if any between a subsonic round and a supersonic round without using a suppressor.

I also agree with the NATO solution - 124gr, preferably in +P, is your best bet with FMJ. Ballistically, a 115gr and a 124gr are nearly identical with the edge in energy at all ranges going to the heavier of the two with little to no loss in relative velocity. In FMJ, 147gr make for a better long range cartridge or use with suppressed weapons.
