RE: Federal Fusion vs. Core-Lokt's
Federal's version of the Core-Lokt is actually called Power-Shok.
I use them in my .308, and it's the most freakin' accurate thing ever to exit my rifle. The velocity is stronger, as is the recoil, but it doesn't bother me, anyway, the Powershoks group one inch higher than Hornady SST ballistic tips.
Try the Powershoks and see if they work well in your rifle, they only cost $13.40 or something at your local Wal-Mart, and twice as much at your local gun store.
