Buck,
I personally am a one load for ALL type of person. Sicne i got the rifle, thinking of Africa, Elk, Moose, bear, deer, hogs, etc.....I decided the BArnes X was the best for ALL.
Never tried any other bullet in mine. Not familiar with the Vulcan but it will probably do well on anything.
I usually like heavy for caliber bullets in general and my thinking is to go woth a 286 gr bullet. Recoil while hunting is never an issue and wearing a "sissy pad" while bench shooting helps.....I USE A "SISSY PAD" also, so I can say that!!!
If the crap hits the fan and you need to take a follow up "Texas heart shot" or a follow up through brush, I like the extra weight. Necessary, probably noy but I feel better.
