No, Taylor was not hunting in OZ. The "water buffalo" were of course, Cape Buffalo, as is clear from the notation in his book. But 9 with 7 shots, using solids to score the two doubles, bull and cow, and softs for all the rest, that is really something!

As Taylor pointed out, those 4 1/4" cartridges are hard to resist. If I had the cash to spare, I would be sorely tempted.
