I didn't want to get in, but....it's too hot (weather) to go out. First, I always wanted a 257I, on a Mexican Mauser, to hunt small Hill Country whiteyails, and the occasional exotic. A huge buck will weigh under 200lbs live weight. Shots are seldom over 200yds. If your hunting conditions mirrow these, I think the 257 is a great choice. My opinions on the perfect deer caliber/ cartridge is 7mm, in either the 7-08, or the coolest of them all the 7x57. That said, if shots are on really large deer or shots are longer, I'd go with the 308. capt david
+1 for the 7x57 Mauser. Fits right in the middle between .308 Win and the .257 Bob. Love mine and after all it is the parent cartridge to the .257 Bob.
