Book Review - Applied Ballistics For Long Range Shooting
The author himself defines his most important and original contribution in the form of the flight-data generated for over 170 bullets, having measured the BC and other factors. A reader can say that other authors have already done that, no problem to grant that. But to my knowledge, no one has gone to the degree of coverage present in this book.

While those values are vital ones to feed our ballistics models, and of course, not to counter the authorís own view, I think the authorís essential contribution is the whole book itself. This, Iím saying because it treats the different aspects of the application of fire, from the perspective of a shooter/hunter. Not a theoretical speech on the derivation of the involved physics that is hardly a need for most people.

And in my opinion, thatís a good thing, for the reason that it will help that a good deal of shooters/hunters start to get closer to the important aspect of understanding (and applying) ballistics. The book promotes easy reading and a natural flow of increasing data/facts that the reader can fit to his own tempo.

For this reviewer, itís very easy to get disappointed by entry-level ballistics books. Most of the time, this feeling is overwhelming. Mr. Litzís book is an exception to that tendency, since the covered topics are not only aptly chosen but also well exposed, illustrated and written.

If you want more or have an academic interest, then go to another book, but I can say that most of the time the information provided will leave a great number of readers well satisfied.

The book itself is organized in three parts, of which the second one is perhaps, at least for my criteria, the most interesting one, given its coverage of sound analysis techniques that can assist any shooter/hunter to perform an undemanding examination of his shootingís outcome.

A central subject of the book is the proposed use of the G7 drag model instead of the usual and widely available G1 function. While the general use of G7 (first published in 1958) can be debated, since itís not a good match for other bullets designs, but the more streamlined, ďVLDĒ types. itís nevertheless a good case in point.

Whereas itís clear that the G7 drag function matches more closely the usual low-drag designs used in long range shooting/hunting than the G1 (something thatís expressed in my website since its beginning) I fall short to notice why Mr. Litz says that the velocity-dependence of G1 is a ďproblemĒ, when the same dependence is there with G7 or any other ďGĒ function, because thatís simply unavoidable.

In my estimation thatís perplexing, since thatís the very reason for having a number of ďGĒ functions and not an argument in itself when debating the merits of G7 as a better function to match the current designs, something that was clear for the last fifty years.
Publisher's Note: The book can be purchased at the LRH Gear Shop
Both G1 and G7 will respond in the same manner, yielding the same amount of error in drop predictions, given the same variation of, for example, muzzle velocity. And as expected, both will show the same ďresilienceĒ to uncertainty in their determination.

No doubt that the work done by the author to flight-test over 170 bullets, is by any standard, a fantastic gift. Itís worth mentioning that along the BC values (G1 and G7) the most critical figure of Cd (Coefficient of Drag) is also published.
