I love all of them. I currently have .240, 257, 270, 7mm and 300 Weatherby Rounds. I use the .240 the most, for prairie mule deer and white tail. The 300 Weatherby has a muzzle break on it and recoils like a .243. The wife is going to use it for a buffalo hunt if she can ever draw a tag for the Wyoming license. I love the .257 but have not used it. I have never fired the 7mm or .270 weatherby.... maybe this coming summer.
