Kitch: I have three 257 Weatherbys and the 2K round count sounds about right. Mine went about 2400 before barrel replacement and I was meticulous about three shot groups then cooling. Without question, at least in my experience, the most lethal killer of deer I've ever experienced. I can tell you that not one deer has ever taken a step when shot with either the 100gr Hornady or the TTSX at ranges from 25 to over 350. It's a great cartridge, but you must be judicious with barrel care. jorge
