Looks like promising results! Should you want more options, perhaps the bullets used or designed for the 300BO? The 110gn Barnes black-tipped TAC-TX has a minimum velocity for 2x expansion of 1350 with the factory recommending sticking with 1450 or faster for reliable performance. Works very well on deer at ~2300fps. It was one of the lowest terminal velocities requirements I found in a rifle bullet.
