African Rifles & Cartridges I bought for $10 at local used book store was far better deal, but TWs book is worth the $25 I paid @ Amazon for it. 'The rifle.....' by S.R. Turesdell was more interesting.
I believe the 'Bible' of 'Worshipful Members of I'm goin to 3rd World Country to Hunt' is 'Any Shot You Want....Rifle Manual' from A-2.
TW's book is not w/o errors, for example, H&W and Heym do not use Johanssen action. In fact, last I looked Johanssen used Eastern European actions sold by Prechtl. You know, that's Gottfried Prechtl from Weinheim, the maker of famous GOL marksman's rifles.
Heck all one needs is Heym .375 bolt gun and 80 rounds of ammo + 50k (just make sure it shoots well in your rifle and it's loaded with Swift-A-Frame and Speer Grand Slam African Tungsten core solids).
