First off I'm no long range hunter as I haven't developed the skills yet, but it is a goal of mine to extend my range. So please bare with me if I ask some elementry questions. I am currently planning on having a .257 Weatherby built with a 28" SS Pacnor barrel in number 5 contour. Initially I thought about having it fluted but on further contemplation I'm thinking of leaving it alone. It will be built on a Rem. 700 ADL action and bedded in a McMillan stock, possibly the A2? Weight isn't a huge factor but I need to be able to carry it from time to time, so I don't want a rifle that weighs over 15 lbs. My intent is to use the rifle specifically for deer (both mule deer and whitetail) and antelope. It may get some use on coyotes as well if opportunity knocks. I live in the wide open country of eastern Montana, where shots can be from point blank to as far as one cares to shoot. Personally I want to be deadly from 400 to 600 yards. I know that may not impress the experts here, but it's a distance I feel comfortable with starting my adventure into long range shooting. Is there any real draw backs to the .257 Weatherby that I should know of for the intended purposes I have? What would be the maximum range the .257 Weatherby would be considered effective for killing deer sized game? Man, I hate sounding like such a greenhorn, but I got to start somewhere.
