I have a question concerning bullet selection in the .257 Weatherby Magnum. Here are the facts: I have a load worked up using the 115 grain Ballistic Silvertip with a muzzle velocity of 3400 fps (chronographed). It shoots sub-m.o.a. all day long if I am on my game. Here are the assumptions: I will likely hunt antelope and mule deer with my .257 WM. Don't believe in using it for elk as I think it to be too small and I already shoot a .300 Win Mag at them. I have been juggling a lot of different bullets through my head that "would do the job better", but I have to answer the latest nagging question. That question is, for the game listed do I even need to worry about changing bullets. Is the bullet I am shooting constructed well enough that my thoughts on changing are a complete waste of time? What have been your experiences with the 115 grain Ballistic Silvertip out of the .25 caliber rifles...especially high end velocity?
