There are a number of good books on the market that focus on ballistics; internal, external and terminal. They are written on several levels, directed at different audiences, quite probably with different intent. “Modern Exterior Ballistics”, Robert L. McCoy which actually includes “The Launch and Flight Dynamics of Symmetric Projectiles” in it’s title, is an excellent book for folks who have an affinity for math, or perhaps would like to write a good external ballistics calculator. I know it worked for me, as it was the first book I handed to someone who actually knew how to use its contents. The information in this book also applies to cannon fire, battle ship projectiles and rockets, in the event you firearms interests evolve to a larger scale.
I think everyone with an interest in firearms should have a copy of Rinker’s “Understanding ballistics”. It is written in language, and with examples, that are understandable and useful. If you like to play, “I wonder how hard that would kick?” or would like to know what influences a bullet in flight, “Understanding Ballistics is a handy reference book to have around. “Modern Practical Ballistics” is probably a good information bridge between these two types of books.
“Modern Practical Ballistics” contains information that is specifically tailored to firearms and firearm projectiles, so there is little guess work in determining correct application of a formula. The math is laid out in a building process, that starts with the law of gravity, progresses through velocity and streamline qualities of a projectile, and ends with Coriolis Acceleration and Gyroscopic effect as bullet path influences; taking into consideration of the rotation of the earth when determining point of impact, and drift caused by the uneven face of a bullet in trajectory. What separates Pejsa from other earlier authors of ballistic calculation, is his original work that led to a set of simplified formulas and greater accuracy of final results.
There is an interesting section regarding the establishment of downrange impact energy, based upon the measurement of recoil. If you read this section, I think it offers an understanding into current equipment that approximates chamber pressure based on firearm recoil acceleration.
The book is well written, well documented and very open in explanation of underlying theory. The copyright date is 1989, making it one of the most modern publications dealing with this topic. I have a hardcopy edition that may be out of stock at most popular outlets. There is a paperback version that is typically in stock and sold for a couple of bucks less.
Thanks
