Welcome to Thunderbird Cartridge Company, Inc (TCCI). We have been providing ammunition and components to the American shooting public for over 50 years. We specialize in .50 BMG ammunition and components. We have ammunition and components for rifle, pistol and shotgun plus black powder for the folks that enjoy front stuffers. Please note that if you go to our powder store there is a separate shopping cart because of the hazmat items, therefore there might be two separate places that require your credit card. Please read our "Information Page" for details. Welcome to our new website. Thank you for your business.
