"I either want an exit and will sacrifice BC, or I want detonation with a lot of BC."
That's a head scratch-er. I have shot a handful of deer with almost the same loading but at 100-300 yds. Performance has been good. At longer range I would have expected less expansion and more penetration. These were smaller Texas Mule deer and whitetails but maybe not enough to make a difference.
Which parts a head scratcher? My bullets didn't do what yours did? If so, welcome to hunting...
