context_page_description: The .410 bore, is the smallest caliber of shotgun shell commonly available. A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control. The .410 started off in the UK as a garden gun along with the .360 and the No.3, No.2 and No.1 bore rimfires. 410 shells have similar base dimensions to the .45 Colt cartridge, allowing many single-shot firearms, as well as some derringers chambered in that caliber, to fire .410 shot shells without any modifications.
context_section_description: The small size of the .410 bore makes it popular for use in compact firearms carried for emergency use. These are often combination guns, with a .22 Hornet or .22 rimfire rifle barrel mounted over a .410 bore shotgun barrel.
  The Snake Charmer is a .410 gauge, stainless steel, single shot, break-action shotgun, with an exposed hammer, an 18 1/8 inch barrel, black molded plastic furniture and a short thumb-hole butt-stock that holds four additional 2 1/2 shotgun shells. These light weight 3 1/2 pound guns have an overall length of 28 1/8 inches and will easily fit under a car seat. They are commonly used by gardeners and farmers for pest control. It originally sold for $89.95 and was marketed as a general purpose utility shotgun perfect for "Fishing - Hunting - Camping - Back Packing - Survival - Home Defense - Truck or Jeep Gun."
  The Savage Model 24 is an American made over and under combination gun manufactured by Savage Arms. The basic .22LR over .410 gauge model weighs 7 pounds, has 24-inch barrels and an overall length of 41-inches. It may also be disassembled for ease of stowage. Its predecessor was made by Stevens and sported a tenite stock and forearm. In WWII, 15,000 were ordered and issued in air crew survival kits for Army Air Force bomber crews to be used as survival arms in the event they were shot down.
  The M6 Aircrew Survival Weapon was made for the US Air Force, with a .22 Hornet rifle barrel mounted over a .410 bore shotgun barrel and was first issued in the Korean War. The military also lists an aluminum .410 3" shell with a rifle primer as standard issue under the ammunition inventory name M-35. The civilian version Springfield Armory M6 Scout has a .22 rimfire or .22 Hornet over a .410 bore shotgun barrel.  The original M6 Aircrew Survival Weapon had a 14-inch (360 mm) barrel, the same length as the stock, and folds in half for storage, making a compact package. With the short barrel, this is legally classified as an any other weapon in the United States, so the M6 Scout is made with 18.5-inch (470 mm) barrels for civilian sales. Special flare cartridges in .410 were issued with the USAF model.
