Dang, first it is hard to find an authentically or correct (fiction) book regarding guns and shooting (nothing like reading about a tactical rifle in .444 marlin.) But yes, All of Stephan Hunters books are good. However, I do have one "fiction" read to recommend, "The Long Rifle" by Stewart Edward White. It is the story of Daniel Boone's rifle..
Non Fiction reads, well I have quite a few, but I'll mention a few of my favorites.
For Capstick fans; "The Last Ivory Hunter", Saga of Wally Johnson. Tells it how it is hunting Africa in the 30's-60's, even has a story about using the "left-overs" from a lion victim for bait.
Elmer Keiths book; "Hell, I was there" is the classic,classic.
"Weatherby" by Grits Grisham is the story of Ed & how Weatherby came to be. Very well written and interesting.
"The Mad Trapper of Rat River"; Story of the infamous Albert Johnson. An old Charles Bronson movie was based roughly on this true story, (the one where he is running across the mountains being chased by mounties).
"Trophies of the Heart" by Russell Thornberry.. Some serious Moose and Whitetail hunting there...
"Alaskas Wolf Man" by Jim Rearden. Story of one of Alaskas first "Game Warden's"
Love to see some more titles listed for ideas.. I gotta go order that "Shooter Galloway" book, hope PS still has it...
