I disagree. The 240 & 257 Weatherby cartridges are unquestionably exceptional long range hunting calibers. Probably more so today than when Roy Weatherby developed them 60 years ago because modern manufactured bullets can de made to perform more reliably at these higher velocities.
Agreed. You can get better barrels today. You can get far better bullets. And there are lots more choices in potential slow burning powders. I would enjoy reloading for one.
I always thought .240 WBY would make a great long range deer and antelope rifle. And if you got a chance at a coyote at extreme range, he would be in trouble!
