Cartridge Collecting / Identification

This site’s main purpose is to provide users with assistance on ammunition/cartridge identification, headstamp identification and general ammunition knowledge for centerfire, rimfire and shotshell cartridges. Because I have a DVD/USB for sale with very detailed information on headstamp identification, headstamps on this page may not be as up to date but will still be left for users to use free of charge. Enjoy primitive, civil war, military, sporting, wildcat or general cartridge collecting?... this page and the available DVD/USB are for you.

As an avid cartridge/ammunition and shot shell collector, I have dedicated this site to the Cartridge Collectors and Law Enforcement Agencies who find this hobby exciting and historical.  There also does not seem to be a lot of web space or information readily available for cartridge information, thus this site was created back in 1996. This site is not intended for, nor does it contain any gun information and very little in the way of re-loading or modern shootable ammunition (ex: boxes of ammo for sale). But you will find many collecting resources.
