http://www.patreon.com/ForgottenWeapons Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forgotten-weapons Today I would like to introduce you to Jack, who runs the Cartridge_Gram account on Instagram. Ammunition researchers and collectors are a somewhat rare subset of gun collectors, and theirs is a subject that is often overlooked. Jack is posting some pretty cool stuff, and I look forward to seeing his project grow!
