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.
The .45 BPM cartridge was developed to allow for black-powder loads of more than 40 grains. This gives the converted Colt Walker the convenience of using self-contained cartridges and the advantage of loads beyond the 40 grain limitation of the .45 Colt cartridge and provides the added benefit of moving the bullet closer to the forcing cone as ...

Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...
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.
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
This magnified image of H110 illustrates propellant spheres passed between rollers to produce a uniform minimum dimension. Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [1]) is a form of nitrocellulose used in small arms cartridges.
Ivory powder measure used to provide a uniform amount of gunpowder for a muzzle-loading firearm before cartridges were available. A powder measure is a device for dispensing consistent amounts of smokeless powder or black powder as charges for handloading cartridges used as small arms ammunition. a typical volumetric powder measure
