These are both more energetic by mass than black powder and can produce higher velocities and pressures. Triple Seven is a volumetric substitute for black powder, and due to its higher velocity, it is recommended to reduce the load by 15%. [11] The carbon-based fuel burned in this case is from the sugar family, not from charcoal.
QuickLOAD has a default database of predefined bullets, cartridges and propellants. The database of the more recent versions of QuickLOAD also include dimensional technical drawings of the predefined cartridges and for most cartridges photographic images. Data can later be imported or entered by the user to expand the programs database.
Hodgdon's product line includes Pyrodex and Triple Seven, which are modern substitutes for black powder and intended for use in muzzleloaders and certain antique firearms. Consequences of black powder's easy ignition by sparks or static electricity make manufacture and storage hazardous. The sole factory of the United States' largest 20th ...
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]
Small business owners should not forget about a rule — currently in legal limbo — that would require them to register with an agency called the Financial Crimes Enforcement Network, or FinCEN ...
The 7×61mm Sharpe & Hart Magnum belted cartridge (A.K.A. 7mm S&H Super [1]) was developed by Philip B. Sharpe and Richard (Dick) Hart in the 1950s. Some articles claim it was based on the .300 H&H Magnum case, [ 1 ] [ 2 ] while others claim it was based on the 7x61 MAS M1907 case.
