Robert L. McCoy

1937 - 1998

Bob McCoy was a distinguished ballistician who worked at the U. S. Army Ballistics Research Lab for almost 30-years doing theoretical and experimental work on everything from .22 bullets to large cannon shells. Over the years you may have read some of his articles in Precision Shooting, Very High Power and other gun magazines. During his career he received three of the government’s highest civilian awards, served on the U. S. Olympic Shooting Sports Research Council, and finally passed on his knowledge to the shooting fraternity by writing “Modern Exterior Ballistics.”

“Modern Exterior Ballistics” is a technical book, largely aimed at professionals with a technical background. However, Bob was a committed shooter. Therefore large parts of the book are accessible to amateurs, and many of the results are simple enough for a scientific hand calculator. In particular there are some beautiful photographs of bullets in flight.

Unfortunately, Bob didn’t have much time to enjoy his achievements. He signed the Preface to “Modern Exterior Ballistics” on March 1998 and died April 29, 1998 before his book was published. Bob’s many friends included a dedication in the published work, and continue to honor Bob by watching over his final work. Bob’s friends have compiled a 20 page document of corrections that they are making available on-line.

The corrections are in a PDF file. If you click on the link below, many browsers will just open the file, as they recognize this standard format. Be patient, it may take a minute or two for the first page to display.
