it is a bonded bullet with a flat base heel to it
Sounds like a Speer Deepcurl to me since the Deepcurl is essentially the same as the Fusion bullet but with a flat base. So the Fusion should be a little more accurate at longer range, but under 300 yards or so you probably wont notice a whole lot of difference other than what the different powder charges cause. So would one be better than the other? Depends on what you're doing.
On the other hand, if it's been manufactured especially for Wal-Mart, you may wanna stay away from it
