Nope, not my choice for "dangerous game". Can the 6.5CM kill the grizz, of course. So can a .260 Rem, 6.5/284, etc. all with partitions. Still one of the best bullets.
However, his statement that a 30-06 with 180 is really no better is absurd.
"Many people will thumb their nose at the Creed for being too little, but opt for the classic .30/06 with 180-grain bullets. Hell of a cartridge, no? Indeed. Two world wars. But do you really believe that .914 millimeters difference in diameter and 40 additional grains of mass is going to make a huge difference in how quickly you can kill a deer, elk, or moose? Larger, more powerful cartridges can deliver more damage and devastation—and they are generally more forgiving when it comes to impact with heavy bone and less-than-perfect shot angles. How much more? That's debatable. As a baseline, if you're choosing and taking ethical, careful shots, a good 140- or 143-grain 6.5mm bullet will kill stuff just as dead—often just as quickly as bullets that are a little bit larger, fired at similar velocities."
No its not debatable IMO for DANGEROUS GAME. But that's JMO.
