I've hunted bears with a .30-30 back east and never felt under gunned. Unless it's a griz or polar bear, I'd feel just fine with a .257 Wby.

Roy Weatherby killed a cape buffalo with a 100 grain round from a .257 Wby, so I don't think it's under gunned for anything in North America.

It's an improvement in terms of trajectory over the .270, which is an improvement over the .30-06 sprg. It's an incredibly flat shooting round.

I like the .270 Win alot too, but I always wanted to shoot with a Wby chambering.
Several gun writers have called the .257 Wby a 'Mouse to Moose' caliber. It's also a favorite for plains game in Africa.

Chuck Hawks says this- "The bottom line is that the .257 Weatherby Magnum is perhaps the ultimate ultra-long range medium game cartridge."

I'll let you know from personal experience soon enough though!!!!
