FREE RESOURCES
In the course of researching the topics treated in this website, we come across materials that we find exceptionally useful and may be of interest to our readers. These materials are either in the public domain, or permission to distribute them has been granted by the copyright owners. Here, you will find books, periodicals, articles, drawings, and videos which our readers may reference free of cost.
We also offer several other information resources which we have authored and make available on this website free of charge. These include a bibliography covering the design, making and testing of guns and ammunition; a glossary of terms related to those subjects; and a series of essays categorized as “Researched Articles”, which are formal presentations of specific topics in firearms and ammunition technology. Researched Articles are papers supported by citations, and which follow a format which is described on our NOTICES page. (Under the heading of NOTICES REGARDING EDITORIAL PRACTICES, see Rules Applicable To Researched Articles.)
The materials we make available on this page are for the most part in the public domain because of their age; the copyrights on them have expired. This means that they reflect old technology which may no longer used commercially. However, we provide them to our readers because they illustrate processes which may be useful on a small scale, or they show processes which we envision as easily adaptable to to modern reduced scale fabrication techniques, e.g., CNC machining and additive manufacturing processes.
