I just came across this about two weeks ago. Pretty cool they are coming out with their own "handgun hunting" specific bullet and ammo line.

I really like the concept of the bullets design, but only achieving 200grs for thier 454 casull and 460 Smith bullets gives me some doubts. especially when Barnes was able to get atleast 250grs out of their XPB for the 454. I haven't seen a listed velocity yet,but in my mind it will have to be pretty high to get the performance out of THAT light of a bullet
