I've seen data on them, but only in the Alliant 2011 manual. I haven't seen any except those loaded in the past 12mos in Federal Factory ammo as so-called "Fusion" ammo..
As another poster related above, the Speer Deep Curl is essentially the same bullet.
They are so new, they haven't hit the normal supply chain yet.
If they are indeed as good or better than the long-standing Speer "Hot-Cor" bullets, they are indeed onto something. I've gotten excellent accuracy and good game performance for the past 30+ years. I hate to see them make radical changes and drop them......
I expect that the new bullets will become 2-3x more expensive however if they become popular. ie: difference between Rainier plated vs. Speer "Gold-Dot" which are all now called "deep curl" bullets now.......As it is now, the plated bullets are a less expensive alternative to replacing old tooling and is cheaper than "bonding" conventional cup and core bullets.....
I suppose well soon see!!!
Personnally I'm looking foward to trying some of the new PowerPro 2000 and 4000 powders....
