I think if a large poll was taken within experienced hunters it would be a landslide in favor of the 300 win mag for elk. I am in no way saying that a 257 won't kill elk,just saying the 300 win mag will do it better and in more situations it will make a clean kill.There are many very experiences hunters that would even say the 257 is very marginal.Look at energy levels out there at 400 yrds between the 2 rounds and look at the bullet weight difference and the wound size difference.I can find no advantage to the 257 weatherby on elk.Not sure why on this site there are so many advocates for small calibers on elk,sorta strange to me.Kinda like saying the 22 mag is the perfect all around deer rifle. A mature elk is 3-4x the size of a mature deer.While the 257 weatherby may be a strong canidate for a all around deer rifle, elk are a whole nother critter and a heck of alot thicker ,stronger, and heavier boned.
