I handled the Savage HH in .308 when they first came out.
To me, for a blind-magazine rifle, it seemed like it would be unnecessarily heavy to hunt with. Now, I don't know about the .223 version of the HH. Maybe it's trimmer and lighter.
But if you're going to be toting the thing around, I'd consider the rifle's weight relative to other choices in the same chambering, like that Ruger American Predator.
