.360 bore

The .360 bore is one of the smallest shotgun bores. Its main uses included collecting ornithological specimens, pest control, and self-defense, often concealed in walking stick or cane guns. The .360 bore was first created by Eley Brothers Ltd, a London based ammunition company founded in 1828. A .360 bore load is often defined as a "2 inch orange-red paper cartridge with a brass head and rolled turnover, white top wad and loaded with No. 5 shot".
