Alvah Buckmore, Jr., a United States Army veteran, is a self-taught expert on small arms ballistics. He has gained national and international recognition as a pioneer on this subject. He taught himself advanced mathematics and developed the skills and tools to work out the mathematical relationships of physical phenomena, starting off with the theory of transfer of energy, theory of penetration, field-effect, and the effect of field-effect over trajectory and time. Among several other new theories in interior, exterior, and terminal ballistics, he finally had enough material to write an entirely original book on the science of small arm ballistics, working over a period of more than 20 years.
