FWIW, I use my M70 257Wby for ringing steel, Pronghorn, deer in open country, and occasionally for calling coyotes. Anyone who can put up with 270Win/30-06 type recoil LOVES shooting the 257. It's light enough to carry on long walks or day hunts, and just heavy enough to settle down fairly quickly as well as enough weight to make it fairly pleasant during summertime steel-ringing sessions.
The .264 would benefit from a shortened ejector/bolt stop, 3.6" mag box, and a lengthened ejection port.
