An 87 grain SP would be good as well as the 75 grain V Max.
I always felt the 85 grain Ballistic Tip was too tough to be a good coyote bullet.
Used the Sierra 90 grain BTHP on a few deer, should be okay on coyotes although it may be a fuzz tough as it always shot through our midwest whitetails.
What bullet are you currently using for antelope/deer?
Never used the 100 grain Sierra GK on coyotes but I would have tried had one ever came along while I was carrying my Bob loaded with that bullet.
