I don't think it will die, especially with the semi-renaissance owing to AR-10 platforms. I've used the .308 and the .338 on black bears. While the .338 doesn't make them any deader, I've been much happier with the holes for blood tracking.
So far, I've been using the 200-grain Fusions. An engineer at Federal suggested I give their Vital-Shok a try, and was going to buy some. Then, about two weeks ago for reasons I do not understand, the price of this particular round almost doubled overnight. They were like $27/box on several websites, then all went to $45-$50. What the hell?
I also tried their trophy copper at the range. In my rifle, it groups well, but about 2" low (IIRC).
I tried to resist the pull of the cartridge, but CDNN's $400 deal on the scoped Model 11 was too much for me.
