Found a copy of Fred Bear's Field Notes at a library last week and read it. He was very honest about his shots and experiences. Amazing how many liver and femoral artery hits yielded him trophies, including a liver-shot tiger taken at about 100 yards with an arrow. He was using broadhead arrows instead of handguns, but it's worth reading if you can find a copy because of his straightforward, honest style.
Of particular interest was a hunt on Marajo Island, Brazil for Asiatic buffalo. This was the same kind of hunt that Peter Capstick wrote about in one of his books. As with Capstick's hunt it was also during the rainy season, and with the same Guide Capstick used. Unlike Capstick's hunt, Bear's hunt was about 8 or 9 days instead of 2 days, and it didn't seem to be the exhausting "in extremis" adventure that Capstick describes. Bear did conclude that Asiatic buffalo on Marajo were the wariest animals he'd ever hunted.
