Little bit off topic, but since double rifles are the premier Dangerous Game rifles, I thought I'd see if it fits...

Terry Wieland has just released a new book, "Dangerous-Game Rifles". I've only just begun to read it, but so far has been entertaining and educational (for a non-double owner like myself). Highly recommended if you're interested in hearing Terry's thoughts and his, as always, impeccable research.
