If I were to stretch things, I'd not hesitate to sling a 140 AB or 150 BT on Elk. No doubt the 160s never let folks down.
They ever get a good line up of heavier .277 hunting bullets, twists might be bumped up.
I ran 150PTs at 2850, not a max fps load b/c of powder choice, but they will plow a mule deer end to end at 250-275 yds from neck to hind quarter
