Robertson - The Perfect Shot

Taylor's book - African Rifles and Cartridges

Any of the old books on African hunting where they decribe the hunting and rifle.

I have looked at some of Elmer Keith's stuff and found it quite good.

I have found reading to be one of the best ways of gaining knowledge.

Hope this helps.
