Military rifle propellant was manufactured in batches in a procedure taking about two weeks [7] from treating cotton linters with nitric acid, through curing the extruded grains to evaporate excess ether and alcohol, and finally coating the dried grains with DNT and graphite.
The differences between the two are the bullet shape, the types of powder used, and that the case of the 12.7×108mm is 9 mm longer and marginally more powerful. 14.5×114mm : The 14.5×114 mm is a heavy machine gun and anti-materiel rifle round used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries.

Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants such as cordite.By the late 19th century, lead-alloy bullets were being enclosed within a jacket of stronger mild steel or copper alloyed with nickel or zinc to reliably impart stabilizing rotation in rifled barrels.
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
