TC,
The Fusion is a "bonded" bullet and while they may not penetrate as deep as a Barnes TSX I would consider the Fusion to be a better bullet for deer on down and would have no qualms using them on moose with a 6.5X55..
Federal and Speer are owned by ATK and Speer is coming out with a new bullet (Deep Curl) this year which I suspect is the same bullet as the Fusion. They are both a plated bonded bullet and they are priced the
same as the HOTCORE bullet that they are replacing over time..
If the relative cheap Deep Curl bonded bullets are as accurate as the Fusion bullet a person would be a fool to waste $ in the premiums for most hunting situations and esp. for deer..
JMO..
