Burning rate moderator: Smokeless powder is a type of propellant used in firearms and ammunition. It burns in a more controlled and steady way. It produces less smoke and residue than traditional black powder. The burning rate of this powder is crucial for a firearm to work properly. If it burns too fast, it can create too much pressure.
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 ]

Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
IMR Legendary Powders is a line of smokeless powders which are popularly used in sporting and military/police firearm cartridges. The initials 'IMR' stand for Improved Military Rifle powder. IMR powders makes a line of various types of smokeless powder suitable for loading many cartridges for rifles, handguns, and shotguns.
This graph shows different pressure curves for powders with different burn rates. The leftmost graph is the same as the large graph above. The middle graph shows a powder with a 25% faster burn rate, and the rightmost graph shows a powder with a 20% slower burn rate. Energy is the ability to do work on an object. Work is force applied over a ...
Orders from countries fighting World War I required determining charges for different European military rifle cartridges, and production volume supported research for improvements. Improved military rifle propellants included a longitudinal perforation converting each grain to a tube with a progressive burning interior surface allowing a more ...
Bulk powders were intended to offer advantages of smokeless powder for use in firearms designed for black powder. Charges of bulk powder are loaded in the same volume appropriate for black powder. Early formulations including partially nitrated cellulose with potassium nitrate or barium nitrate were more successful in shotguns than in rifles.
