Infrastructural Rifle Ammunition

A brief list of rifle ammunition that have been employed by the Infrastructural Army as of 36 IA

1: 15mm lead cylindro-conical bullet, the first bullet used by the Infrastructural Army used by the Type-1R and Type-2R rifles as well as the Type-1P and Type-2P pistols. An aerodynamic design well suited for use in rifled muskets thanks to a concave rear, it was more accurate, easier to load and more damaging than a round ball while being just as easy to make. Copies of this design and derivatives were a major contributor to the rifle wars their associated arms races in lands to the west due to the ease with which the design was replicated.

2: 11mm lead slug for a Type-3R rifle

3: Paper cartridge for the Type-3R/a rifle, introduced in 11 IA this paper casing contained a measure of black powder as well as a percussion cap and made the Bolt Action system viable. Paper mache was used to seal the breech. These cartridges were fairly easy to make by hand and would remain common throughout the war of unification. The cartridge disintegrates after firing with most of it being expelled out the barrel. The last paper rounds were made in 24 IA, with the remaining stock being used in marksmanship practice or enforcer use over the next 8 years.

4: Brass Cartridge for the Type-3R/b rifle. Introduced in 17 IA this new cartridge required mechanical drawing equipment to make, but had numerous advantages, being more durable and resistant to moisture. It's increase durability could be used in automatic weaponry. While the cartridge needed to be removed after firing, fouling was much less of an issue. During the war of unification it was standard policy that soldiers collect spent cartridges after battle so they may be reused or recylced. It remains the most common Infrastructural cartridge in use by Infrastructure.

5: 7.5mm slug for the Type-4R rifle: lead in a copper nickle alloy jacket. This projectile has superior ballistics to it's predecessors

6-7.5x60mm cartridge, the next generation of Infrastructural ammunition using nitrocellulose as a propellent as opposed to black powder. As such, this bullet's charge has fifty percent more power when compared the the older 11mm ammunition while leaving far less fouling, enhanced by other improvements in it's design including it's bottleneck configuration. Even so there is currently a production bottleneck for nitrocellulose which prevents it from being widely used.
