As the name suggests, shotgun powders are typically used to load 12 gauge, 20 gauge, and other shotshell sizes. This gunpowder is optimized for shotguns, but sometimes it's used by reloaders for pistol cartridges as well.
Due to the larger bore of shotgun barrels, shotgun powders are typically double-base (combining nitrocellulose and nitroglycerin) and burn quickly to produce enough chamber pressure to fire shot columns at sufficient velocity.
Shotgun powder is a type of smokeless powder, also known as propellant powder. You'll find in-stock powder for sale below by Hodgdon, Accurate, Alliant, Winchester and Ramshot.
