The C was to indicate the powder burned "cooler" than traditional Improved Military Rifle (IMR) powders. [4] In 1949, he began acquisition of powder salvaged from disassembled Oerlikon 20mm cannon cartridges. This powder resembled IMR 4350 in appearance, and with a slower burning rate, was initially marketed as "4350 Data", and later as 4831. [5]
By 1936 improved DuPont process control produced batches conforming to published reloading data rather than requiring different charge specifications for each batch; [11] and those propellants have remained in production. Non-conforming batches were used to load commercial and military cartridges following traditional testing procedures.
This primer was created specifically to provide reliable ignition for compressed powder charges in large capacity cases. [52] All reloading manuals provide loading data using only this particular primer to develop reloading data for the .460 Weatherby Magnum. In a pinch the Winchester WLRM primer or primers with similar brisance may be substituted.

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 ...
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
The .700 Nitro Express (17.8×89mmR), also known as .700 H&H, is a big-game rifle cartridge.The cartridge is typically charged with around 250 grains of powder, in addition to a two-grain igniter charge (to reduce the tendency of the cartridge to hang fire from such large powder charges). [3]
