why not? it's a caliber that has killed most of the animals on this planet. keep in mind that the single guy who's probably killed more elephant than anyone else who has EVER lived did it with a 7x57. and for the time, it was a 175 grain bullet at 2400 fps, as modern as the could get. you can load a 125 grain bullet at 2900 fps and do just as good or better.
25-06 will not give you the assurance of excessive damage if you have a poor hit, but if you hit what you want to hit, it's over kill. If you hit the chest of the animal, it is more than enough to do the job.
