Firearms Terminology Defined in Online Resources

Confused about the meaning of a term such as “meplat”, “magnaflux” or “obturate”? Need to know the OAL of an unusual Wildcat such as the .218 Donaldson Wasp? Well CCI and MidwayUSA offer handy answers on the web. CCI’s Shooters’ Glossary is a very complete collection of gun-related and reloading terms. MidwayUSA’s GunTEC Dictionary contains short descriptions of hundreds of cartridges, plus definitions of thousands of shooting-related words and phrases. How many of you knew that “Maggie’s Drawers” is “a colloquial term used for the red flag once used by pit workers to signal a missed shot at high-power rifle competitions”?

MidwayUSA GunTec Dictionary

Consulting the dictionary, we learned that “Magnus Force” was not a Tom Selleck TV show. Rather, “Magnus Force is the movement of a bullet in the direction it is rotating (and downward) due to the lower air pressure surrounding it. The low pressure pocket is caused by the effect of the bullet’s fast rotation on the surrounding air.” MidwayUSA’s GunTEC dictionary even includes short “bios” of notable firearms inventors and marksmen, including J.M. Browning, Fredrich von Martini, and Peter Paul Mauser. A serious shooting buff could spend hours browsing the GunTEC dictionary, learning new facts (and a ton of obscure trivia.)
