Opinions: The 9.3x74R is, indeed, marginal for such use, though it is a wonderful caliber if used properly for what it was intended; I own and shoot three of them, one o/u scoped; the other two iron sights, and I love them. Personally, I would never go against a cape buff. with a 9.3. Indeed, should the buff charge, it is fast and brutal; no time to think, only to react. Those conditions are not the best for most hunters, unless they have extensive experience in such situations, and they enjoy living "on the edge." I have a close friend who planned his buff hunt for months. He intended taking his .450/.400, but more experienced hunters repeatedly told him, finally convincing him, to use more caution, and to take his .450, so he did. The buff charged immediately, without warning of any kind, running down into a ravine as it came for them, out of sight temporarily, and when it appeared, it was damn close. Yes, my friend shot and killed the buff, but only a few feet from where he was standing, and the PH said that he had never seen anything like it. The wife of my friend said that it took him months to recover from the shock, and for hours after it happened, my friend was speechless, all understandable. Believe me, he was very happy that he took his .450! When bad things happen, even the most fearless don't want to have only a 9.3 in their hands---at least I don't, that is certain. If you do take unnecessary risky chances, be sure your will is in proper order, for you will not be hunting deer.
