I cant see any reason for killing this animal
Then don't! I enjoy hunting them! Everytime someone I know gets a once-in-a-lifetime tag, I tag along! Someday it will be me!
As far as skill, just knowing the country and finding them in an open area is a skill in it's self. Oh yea, and packing them out! They are huge!
I don't know about the .22-250, though! Might need a solid!
