The Boomershoot is a long range precision rifle event held near which city in Idaho, in recent years, the event has also featured an explosive fireball and an Anvil firing to start the event and entertain the participants?
Anvil firing Anvil firing (also known in the USA as an "anvil launching" or an "anvil shooting") in the USA is the practice of firing an anvil into the air with gunpowder. In the UK this is where black powder is filled onto the top of the Anvil and ignited. If the Anvil did not shatter it was deemed safe to use.
Shot (pellet) Shot is a collective term for small balls or pellets, often made of lead. These were the original projectiles for shotguns and are still fired primarily from shotguns, although shot shells are available in many pistol calibers in a configuration called "bird shot", "rat-shot", or "snake shot". Lead shot is also used for a variety of other purposes such as filling cavities with dense material for weight/balance. Some versions may be plated with other metals. Lead shot was originally made by pouring molten lead through screens into water, forming what was known as "swan shot", and, later, more economically mass-produced at higher quality using a shot tower. The "Bliemeister method" has supplanted the shot tower method since the early 1960s.
