Gleaned from fifty published articles and two previous books; contains much valuable new information for all shooters from novices to experts. Most important, it presents new, simple but EXACT formulas and methods for predicting trajectories out to extreme ranges. An authoritative new book by Art Pejsa, pioneer Honeywell aerospace physicist, US Naval Academy math prof & NRA rifle expert. Covers a wide range of informative topics including the basic fundamentals of physics, with a large glossary, & extensive ballistics tables. A decade of original research by Pejsa has produced a set of new, simple but exact formulas & a method for do-it-yourself ballistics. Easy examples show how to calculate any of the data. A great text for an elementary course in exterior ballistics. The advanced novel methods devised by Arthur Pejsa permit air drag to be modeled precisely by simple, exact formulas for unheard-of precision. The software program computes trajectories, velocity, flight time, wind deflection, etc. with near-perfect accuracy. Other programs assume a fixed drag curve, usually that prescribed by the popular Ingalls Tables, which poorly fit the drag curves of modern, streamlined projectiles. With the Pejsa Ballistics program, velocity & drag data can be matched, permitting unequaled precision. With this program, shooters may, for instance, specify any hit height at any range or a maximum height at midrange. Output data may be in tables or plotted as curves. Ballistic coefficients, recoil, midrange, etc. may be computed as well as effects of temperature, altitude & inclines. This superior program is user-friendly, complete &, above all, ACCURATE enough to serve as the reference for evaluating other formulas & programs.8.5x5.8 inches, 224 pgs.
