I've only seen a few of them used, mostly on game bigger than deer. 150's work fine from the .300 Winchester Magnum out to 400 yards or so, but they're still zipping right along even at 400.

However, my experience with bullets like the TSX, E-Tip and GMX in general is they kill better when really zipping along. Don't see many advantages in them at muzzle velocities much under 3000 fps--except, of course, where non-lead bullets are mandated by law.
