BT's were designed to work at velocities more associated with long range. They can come apart a close range velocities.
I loaded a bunch for a friend who likes them (150 gr.) in '06 and they worked fine. However, they were loaded to a MV of about 2850 fps, and at 100 yds and out they peformed fined on antelope, and deer and weren't too destructive.
Don't know what happend to a 150 gr. from a 7mm Mag. An autopsy report would have been helpful in analyzing the problem.
While BT's have been known to expand too quickly on big game, having the bullet exit a coyote is how I'd want it. Pretty tough to design a bullet that expands quickly in coyotes and stops them in their tracks while, at the same time, giving deep penetration a a critter the size of an elk.
Your Noslers that were designed so the front part expands moderately even at long range, while the back part drives it deep, would be expected to perform well on game of different sizes and at different ranges.
The Nosler BT simply wasn't so designed, and going thru the coyote-- without much expansion-- is a good thing for an elk bullet.
Without a little "post mortum" report, we still don't know why they didn't work tht well on elk. And just because the elk didn't immediately drop with the first shot doesn't mean he wasn't done for or that all those shots were necessary.
