A couple of other tools that folks have found useful:
http://gunbot.net/ (http://gunbot.net/) - Near realtime tracking of who has ammo, mags and reloading supplies in stock.
http://ammoseek.com/ (http://ammoseek.com/) - Ammunition Search Engine
slickguns.com has user-posted deals on guns, ammo, accessories - it is searchable by name, category, etc.

Another one: http://www.wikiarms.com/ (http://www.wikiarms.com/)
