How to use the boombadge::

· Before each use inspect for any damage, if the boom badge is suspected of any failures or damage do not fire or use.

· Always Wear appropriate eye and ear protection

· Load only when the boom badge is cool and free from any embers or any heat or embers that could cause the powder to ignite prematurely. On a stable flat surface, loosen the thumb screws on the side of the boom badge and place the barrel in the upright position, then lightly re-tighten the thumb screws to hold the boom badge upright.

· Place a single cannon or firework fuse (.3mm) (5 second fuse is recommended) into the fuse hole at the rear of the boom badge, push it well into the breech until it stops (making contact with the other side of the barrel)

· Load no more than 12.3 grains of triple 7 FFF or similar grade black powder into the barrel of the boom badge. NEVER USE GUN POWDER, ONLY BLACK POWDER! Pack powder firmly with provided ram rod.  This should provide a tight packing around the fuse ensuring the powder ignites.

· Place in a single 5\16” steel shot (sling shot ammo works well) into the barrel and push down until it contacts the powder with a small amount of force. Wadding is not required but can be used in small amounts behind the steel shot if desired. Less powder may need to be used if wadding is used depending on the thickness of the wadding.

· Loosen the thumb screws and aim the boom badge in a safe direction away from people and animals and toward an appropriate backstop. When desired angle is achieved tighten thumb screws well to prevent the boom badge from changing angles when lighting and firing.

· Light the fuse and retreat to a safe distance minimum of 10ft and wait for the boom badge to fire. After the boom badge fires wait for it to cool before loading again or cleaning.

· If the boom badge does not fire:

     o Wait 5 minutes, return to the boom badge and place another fuse, light as before.

     o If the boom badge still does not fire douse the boom badge with water to saturate the powder and render the boom badge safer to handle after a misfire.

     o Clean the boom badge and attempt the shot again

     o If the boom badge repeatedly fails to fire and a cause cannot be determined easily and without modification discontinue use of the boom badge.

· To clean the boom badge, use rubbing alcohol and Que tips or stainless steel safe bore cleaner. A small pick or pipe cleaner can be used for the fuse hole.  Always clean the boom badge after use to prevent any buildup of excess materials. After cleaning oil is not required but a black powder \ firearm safe lubricant can be used to protect from corrosion, though it should be used sparingly.

· Never fire the boom badge at anyone or anything you are not willing to harm or destroy. Never use gunpowder or high explosive materials as the boom badges are not designed to have high heat elements burn inside them. Never use tightly fitting shot or wadding as it can cause the boom badge to fail catastrophically, resulting in injury. Never shoot from a hand or attached to the lanyard, always place on a safe level surface before loading and firing. Never modify the boom badge.
