The second book won't be out until late this year. It's the revise/update of Safari Rifles, written by Craig Boddington in 1991. (This one will be called, logically enough, Safari Rifles II.) Since then, the book has gone on to become the definitive work in the field, eclipsing even John Taylor's African Rifles and Cartridges. Craig has been on 75 safaris. I will say that again: Craig has been on 75 safaris, and has no axes to grind, so his is the most impartial and best grounded advice available. It's also a Safari Press book. Watch for it.
