By the way, I never posted the results of the Accubond's weight retention after going through that bear. As I said, it went through both shoulders at 78 yards and stopped under the hide on the far side. It started out 200 grains and weighed 133 after recovery -- 66.5 perccent weight retention. According to Nosler, the Accubond is designed to hold 60 - 70 percent of its weight, so it was right on the money.
Nevertheless, that's a third of the bullet's weight shed -- which is why I like the TSX for heavy stuff. There's a difference between kinetic energy and momentum, so a tougher bullet with less KE can often out-penetrate one that doesn't hold its weight. That's why my 180 gr TSX in a .300 WSM at 125 yards outpenetrated my friend's 200 gr Accubond out of a .325 at 78 yards, even though the .325 had at least ten percent more energy.
As has been pointed out here, heavy hard-cast bullets in a .45-70 can be devastating due to their ability to hang onto their weight and penetrate -- especially if they're coming out of a +P load like Buffalo Bore (Garrett Ammunition makes some impressive loads, too). The only problem is the trajectory -- it's not a long-range round.
