Black powder substitute: A firearm propellant that is designed to reproduce the burning rate and propellant properties of black powder (making it safe for use in black-powder firearms), while providing advantages in one or more areas such as reduced smoke, reduced corrosion, reduced cost, or decreased sensitivity to unintentional ignition.
The catch is, in order to send a .30-caliber slug over a trajectory as flat as that 7 mm bullet, about 20 percent more recoil is going to be generated. . . . [A bullet in] 7 mm produces clearly superior downrange performance in terms of delivered energy and trajectory at any given recoil level [compared to a bullet in .30 caliber]. [3]
A black powder substitute is a replacement for black powder (gunpowder), primarily used in muzzleloading firearms. Substitutes may have slightly different properties from gunpowder such as: reduced sensitivity as an explosive, increased efficiency as a propellant powder, different density, and/or reduced ignition efficiency.
A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
A 12-gauge shotgun cartridge in a transparent plastic hull, allowing the contents to be seen. From left to right: brass, propellant, over-powder wad, shot wad, #8 birdshot, over-shot wad, and crimp. A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns.
The downrange facility was a Liberty-class merchant vessel renovated and converted for its technical assignment and renamed the USAS American Mariner.Its measurement equipment complex included C-band, L-band and UHF radars; digital and analog recorders; gyroscope stabilization; timing generators; mode switching; telemetry acquisition apparatus; radiometers and riometers; boresight cine-TV and ...
The wad slug is loaded using a standard shotshell wad, which acts like a sabot. The diameter of the wad slug is slightly less than the nominal bore diameter, being around 0.690 in (17.5 mm) for a 12-gauge wad slug, and a wad slug is generally cast solely from pure lead, necessary for increasing safety if the slug is ever fired through a choked ...
