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.
Using the 100gr. Ballistic tip at 3020...great groups.

Be a hard one to beat for an all around load although you may get a few runners with that bullet as it is reported to be fairly stout for a 100 grain 25 caliber bullet.
That 75 grain V Max will be a lights out bullet but stay off of shoulders.
Shoulder hits may require a finishing shot as this bullet is very fragile, at least when pushed to max velocity from a 26" barreled 25-06.
