Michael Petrov :The correct title to F.W.Mann's book is
"The Bullet's Flight from Powder to Target" with a sub-title of "The Internal and External Ballistics Of Small Arms"
There is yet another explanation on the Title Page as follows"A Study of Rifle Shooting with the Personal Element Excluded Disclosing the Cause of The Error At Target.
The book as originally published by Munn & Co in New York in 1909.
Wolfe republished it in 1980
