I would not take a 25-06 or 257 out to hunt elk. However if that is what I was carrying when I found an elk I would not run away with my tail between my legs.

I have taken elk with a 270 and a 308 and as my handle suggests an 8mm and some more in between the 270 or 308 is a good starting point for an elk rifle.

As for bullets shoot the bullet that you have confidence in. I killed many elk with standard bullets. Used 154 grain Hornadys in a 7 mag for years then some one convinced me that I "NEEDED" premium bullets to kill elk. The elk that I shot with premium bullets died just the same as the ones shot with standards.

My point is elk are not armor plated but they are larger and tougher than deer so if you hunt with a gun of less than ideal power make extra sure of your shot placement.
