QC is hard enough to control for most companies when everything goes right. If they make a bullet that is supposed to work in a designated velocity range and the customer pushes it a lot faster, the results are typcially poor. The Hornady may be fine at the velocity you want to push it, I don't know. I would speak to someone at their shop before I hunting with it, though.

It may shoot little groups, but may not able to handle hitting bone at those speeds. I'd take a bullet designed to operate at those speeds and a little less accurate than vice-versa for a hunting bullet.
