It will likely work great. It's at least bonded (or at least bonded the same way the fusions are). The fusions tend to be soft, on average, they lose some weight but overall hold together pretty well. Up close they make big buttonheads and mostly stay together close up but farther out you still get a textbook mushroom.
If it's made for the Grendel at 2400 fps all that says to me is that out of a creedmoor it'll be a versatile bullet it will expand at longer ranges and lower velocity and probably open instantly and mostly hold together close up. I've found deer have noticeably shorter dead runs when hit with light, fast, soft bullets, for instance nosler 120gr BT's in 7mm.
