    Fouling shot: A fouling shot is a shot fired through a clean bore, intended to leave some residue of firing and prepare the bore for more consistent performance in subsequent shots. The first shot through a clean bore behaves differently from subsequent shots through a bore with traces of powder residue, resulting in a different point of impact.

  3. Gunshot residue - Wikipedia

    en.wikipedia.org/wiki/Gunshot_residue

    A negative result on someone could mean they were near it but not close enough for gunshot residue to land on them, or it can mean that the gunshot residue deposited on them wore off. [ a ] Gunshot residue can also be removed from surfaces by washing, wiping, or brushing it off, so a negative result cannot fully rule out a gun was not fired by ...

    en.wikipedia.org/wiki/Internal_ballistics

    Since smokeless powders burn, not detonate, the reaction can only take place on the surface of the powder. Smokeless powders come in a variety of shapes, which serve to determine how fast they burn, and also how the burn rate changes as the powder burns. The simplest shape is a ball powder, which is in the form of round or slightly flattened ...

  5. Tannerite - Wikipedia

    en.wikipedia.org/wiki/Tannerite

    Tannerite is a brand of binary explosive targets used for firearms practice and sold in kit form. [1] [2] The targets comprise a combination of oxidizers and a fuel, primarily aluminium powder, that is supplied as two separate components that are mixed by the user.

  6. Powder burn - Wikipedia

    en.wikipedia.org/wiki/Powder_burn

    A powder burn is a type of burn caused by exposure to the combustion gases which are expelled from the muzzle of a firearm as it is fired. [1] Powder burns only occur when the individual is in close proximity to the discharging firearm, as the gases quickly dissipate. [ 2 ]

    The shot was carried on a specially designed iron barrow or two-man litter and, in the era of black-powder cannon charges contained in cloth bags, occasioned much fanfare and notice as it was conveyed to the cannon muzzle as the red-hot projectile would easily ignite any carelessly handled loose powder.

  8. Squib load - Wikipedia

    en.wikipedia.org/wiki/Squib_load

    Squib rounds are possible in all firearms. They are most often caused by negligence in the powder loading process (insufficient or no powder load), or a failure of the primer to ignite the powder at all. In the case of no gunpowder in the cartridge, the primer, when struck, produces just enough force to push the bullet into the barrel but no ...

  9. Firearm propellant - Wikipedia

    en.wikipedia.org/wiki/Firearm_propellant

    Black powder produces gas at a predictable rate unaffected by pressure, while the gas production rate of smokeless powder increases with increasing pressure. [6] The possibility of runaway pressures caused smokeless powder to destroy many firearms designed for black powder and required much more precise measurement of propellant charges.
