Can you kill an elk with a .25 automatic if you " do your part"? It's possible but why would you want to? I have seen elk run to the next county with less than exceptional shots from 300 mag and never recovered. Tougher animal than most give credit for. My son was not allowed to shoot an elk until he could handle the .270, about 12 yrs of age. And 22 caliber is foolish and out of the question.
