Sniper Rifle:

.955 Boxer: Based off the .950 JDJ. It uses a milled down 20mm Vulcan parent case. Measures 0.955 x 4.01 inches. The projectile (without the case and gun powder) weighs half a pound and leaves the muzzle at a speed of 2,200 ft/s (670 m/s) generating 38,685 ft•lb (52,450 J) of energy- almost 3.5 times that of the 12.7mm by 99mm round. Creates so much recoil force that a person under 200lbs has to fire this cartridge from a prone position to avoid being knocked over by its recoil.

20mm Vulcan: Invented during the First World War this round has survived the test of time. Originally used in mounted auto-cannons technology has advanced far enough to make firing these out of rifles possible.

.666 Lucifer: A large rifle cartridge invented by a Russian gunsmith in 2135 to be a step up on the .600 O.K.

.600 Over Kill: The .600 Overkill was designed by Robert Garnick of Las Vegas, Nevada. The case is based on the .600 Nitro Express, with a belt added for head spacing and the rim to fit that of the .505 Gibbs [.640 in (16.4 mm)] size bolt face. This cartridge was intended to be the largest bullet that was able to fit in the CZ-550, and was designed specifically for the purpose of elephant hunting. With solid brass bullets, the .600 overkill is able to penetrate 6 feet (1.8 m) into solid oak.

The .600 Overkill fires a 900-grain (58 g) bullet at more than 2,400 ft/s (730 m/s), At this level of power, as the bullet spins down the barrel, the rifle is torqued in the opposite direction, often twisting the rifle out of the shooter's hand. Recoil in standard-weight hunting rifles (10 lb (4.5 kg) or less) is far beyond what most shooters will tolerate. Traditional dangerous game hunting rifles typically weigh more, up to 14 lb (6.4 kg), and have less recoil.

14.5mm x 114mm: The 14.5×114 mm (.57 Cal) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, Russia, and other countries. It was originally developed for the PTRS and PTRD anti-tank rifles, but was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of the BTR series of armored personnel carriers from the BTR-60 to the BTR-80.

12.7 mm x 99mm: based of a WWI anti-tank cartridge. With a high velocity, long range, and high stopping power it is used as a an anti-personnel round.



Repeater Pistols:

.50 A.E. The .50 Action Express (AE, 12.7×33mm) is a large caliber handgun cartridge.

.440 Cor-bon: based of the .50 A.E. basically a rifle round in the parent case of the .50A.E. Higher recoil than a .50 A.E. with greater accuracy and stopping power.

.38 Super Six: based of the .50 A.E. basically a rifle round in the parent case of the .50A.E. Less recoil than a .50 A.E. with greater accuracy and equal stopping power.

.460 Magnum. The .460 S&W round is a lengthened, more powerful version of the popular .454 Casull, itself a longer and more powerful version of the .45 Colt.

.454 Casull: The .454 Casull (pronounced Ka-Sool) is a firearm cartridge, developed in 1957 by d**k Casull and Jack Fulmer. It was first announced in November 1959 by Guns & Ammo magazine. The basic design was a lengthened and structurally improved .45 Colt case. .45 Colt cartridges can fit into the .454's chambers, but not the other way around because of the lengthened case, (very similar to the way .38 Special cartridges can fit into the longer chambers of a .357 Magnum and .44 Special cartridges can fit into the longer chambers of a .44 Magnum).The new Casull round uses a small rifle primer rather than a pistol primer, because it develops extremely high chamber pressures of over 60,000 CUP (copper units of pressure) (410 MPa), and has a significantly stronger cup than a pistol primer. The .454 Casull is one of the most powerful handgun cartridges in production.[3] It can deliver a 250 grain (16 g) bullet with a muzzle velocity of over 1,900 feet per second (580 m/s), developing more than 2,000 ft-lb (2.7 kJ) of energy, although energy levels from common .454 revolvers with 7-8 inch barrels are typically somewhat lower (1,600-1,700 ft•lbf). The round is primarily intended for hunting medium or large game, metallic silhouette shooting and predator defense.

.44 Magnum: The .44 Remington Magnum, or simply .44 Magnum, is a large-bore cartridge originally designed for revolvers. After introduction, it was quickly adopted for carbines and rifles. Despite the ".44" designation, all guns chambered for the .44 Magnum case, and its parent case, the .44 Special, use bullets of approximately 0.429 in (10.9 mm) diameter. The .44 Magnum is based on a lengthened .44 Special case, loaded to higher pressures for greater velocity (and so energy). The .44 Magnum has since been eclipsed in power by the .454 Casull, among others; nevertheless, it has remained one of the most popular commercial large-bore magnum cartridges.

.460 Rowland: The .460 Rowland case is approximately 1/16" (.0625 inches (1.59 mm)) longer than a conventional .45 ACP. However, the overall cartridge length of the .460 Rowland is the same as the .45 ACP as the bullet is seated a bit deeper. This means the practical case capacity for both cartridges is identical. Case length for the .45 ACP is 0.898 inches (22.8 mm) and cartridge overall length is 1.275 inches (32.4 mm). Case length for the .460 Rowland is 0.955 inches (24.3 mm) and cartridge overall length is 1.275 inches (32.4 mm). The purpose of the extended case length is to prevent the high pressure .460 Rowland from being chambered in a standard firearm chambered for the low pressure .45 ACP, similar to the relationship between the .357 Magnum and the .38 Special.


.45 Super: The .45 Super is a smokeless powder center fire metallic firearm cartridge developed in 1988 by Dean Grennell, a well known writer in the firearms field as well as managing editor of Gun World magazine. Born of a desire to update and improve the 1906 era .45 ACP, the .45 Super cartridge is dimensionally identical with the older .45 round, but offers an average 300 foot per second (ft/s) improvement in muzzle velocity. The cartridge was co-developed by Tom Fergerson and Ace Hindman.

.45 ACP: The .45 ACP (11.43x23mm) (Automatic Colt Pistol), also known as the .45 Auto by C.I.P., is a cartridge designed by John Browning in 1904, for use in his prototype Colt semi-automatic .45 pistol and eventually the M1911 pistol adopted by the United States Army in 1911. The .45 ACP has a good reputation for performance.

10mm Super Auto: The 10 mm Auto (10×25 mm, Official C.I.P. Nomenclature: 10 mm Auto) is a semi-automatic pistol cartridge developed by Jeff Cooper and introduced in 1983 for the Bren Ten pistol. It was initially produced by ammunitions manufacturer FFV Norma AB of Åmotfors, Sweden. In the early 22nd century this outdated cartridge was updated with the use of stronger powder and slightly increased length (10 x 32mm) making it far more accurate and powerful than the original 10mm Auto.

.40 Magnum: A special ammunition that has same energy as the .44 magnum at twice the velocity.

.40 Short and Weak: The .40 (10×20mm) is a rimless pistol cartridge developed jointly by major American firearms manufacturers, Winchester and Smith & Wesson. The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the FBI's reduced velocity 10mm cartridge which could be retrofitted into medium-frame (9mm size) automatic handguns. It uses .40-inch (10.16 mm) diameter bullets ranging in weight from 125 to 200 grains (9 g to 13 g). A number of .40 loads with hollow point bullets offer a good combination of expansion and penetration.

9mm x 25 mm: based on the 9mm x 19mm round. This round has stopping power comparable to that of the 45 ACP round

.38 Super Long Colt Magnum: A long cartridge crammed with as much gunpowder as it would fit. This round is accurate at long distances and has the muzzle energy equal to a .45 Super round.







Revolver Handguns:

.700 Nitro Express: In many respects this cartridge parallels the .600 Nitro Express, in that it is essentially a scaled-up version of that cartridge, but is somewhat more powerful, and fires a heavier 1000-grain (64.8 g) bullet. The case itself is a completely new case, not simply another case resized.

.600 Nitro Express: All .600 Nitro Express cartridges carried a 900-grain (58 g) projectile. Early versions were loaded with cordite. While the .700 Nitro is of course larger, the .600 Nitro is the largest dangerous game caliber to have been used during the heyday of African ivory hunting. The .700 was a 1980s creation as a result of a well-to-do gentleman being denied a 600 NE caliber rifle from renowned maker Holland and Holland. Though the .600 was larger than the .577, it was not nearly as popular among professional hunters of the day. In use, a professional hunter would carry this rifle only when expecting a charge, or when the hunter was in the "thick brush", with a gun-bearer carrying it at other times. The rifles chambered for these rounds were most often side-by-side double rifles with boxlock actions made by the Jeffery Company of England. However, Jeffery did introduce their Model 1904 Farquharson-based falling block, single shot rifle in 1904 specifically for the 600 NE

.500 Magnum: The .500 S&W Magnum is considered one the most powerful commercial sporting handgun cartridge by virtue of the muzzle energy it can generate. Cor-Bon (now a Dakota Ammo brand) who together with Smith & Wesson developed the .500 S&W Magnum cartridge, offers several loads which include a 325 gr (21.1 g) at 1,800 ft/s (550 m/s), a 400 gr (26 g) at 1,625 ft/s (495 m/s) and a 440 gr (29 g) at 1,625 ft/s (495 m/s). Compared to the next most powerful commercial sporting handgun cartridge, the .460 S&W Magnum, which can launch a 325 gr (21.1 g) at 1,650 ft/s (500 m/s) or a 395 gr (25.6 g) at 1,525 ft/s (465 m/s), the .500 S&W Magnum produces about 15% to 40% more muzzle energy than the .460 S&W. The .500 S&W Magnum comes into its own when used with heavier bullets, particularly those with weights of 500 gr (32 g) or greater. When possible these bullets should be seated as far out as possible to take advantage of the complete cylinder length, so as to maximize the powder capacity which the case can provide.

.480 Super Magnum: The .480 is a well-balanced cartridge, providing a lot of energy without the recoil of larger hard-kicking rounds. It has been stated by many gun writers, that the .44 Magnum is typically the most powerful handgun an average person can master. The .480 should be able to take that title, as its original Hornady loading of a 325gr JHP, easily surpasses factory loadings for the .44 Magnum, with very similar recoil in handguns of like weight.

.357 Magnum: This cartridge is regarded by many as an excellent self-defense round. The hollow point version enjoys a reputation of being the gold standard of stopping power among handgun cartridges and an "extremely reliable one shot stopper." For big game, such as ungulates and bears, which have a substantially sturdier build than humans, it is inferior to the .500 Smith & Wesson, .50 Action Express, .44 Magnum, .454 Casull, .41 Magnum and other larger magnum rounds. Still, it is a fine small and medium game round and will kill deer very reliably at reasonable ranges if the right loads (140 grain and heavier hollow-point bullets, and solid semiwadcutter bullets) are carefully used by a competent marksman. For further comparison, the .357 Magnum has a higher velocity at 100yds, than its parent .38 special has at the muzzle. Its stopping power on game is similar to the .45 Colt and it has a flatter trajectory. It is a very versatile cartridge, and can be used with success for self-defense, plinking, hunting, or target shooting.

 
Submachine Guns:

5.7×28mm: The FN 5.7×28mm is a small-caliber, high-velocity cartridge designed and manufactured by FN Herstal in Belgium. It is a bottlenecked center fire cartridge that is somewhat similar to the .22 Hornet or .22 K-Hornet. The 5.7×28mm was developed in conjunction with the FN P90 personal defense weapon (PDW) and FN Five-seven pistol, in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge

4.6×30mm: The HK 4.6×30mm cartridge is a type of ammunition used in submachine guns. It is designed to minimize weight and recoil while increasing penetration of body armor. It features a bottlenecked case and a pointed, steel-core, brass-jacketed bullet.

7.92×24mm: The 7.92x24 mm cartridge is a pistol cartridge designed in Belgium by Rik Van Bruaene of VBR-Belgium. The design objective was the development of a cartridge for use in Personal Defence Weapons (PDW), and for use in pistols, submachine guns and carbines. The technical specifications of the 7.92x24 round are much closer to the 9x19 mm NATO pistol round than that of the 4.6x30 mm and 5.7x28 mm rounds more commonly used in PDWs. The 7.92x24 mm is specially designed to fulfill a multicaliber role in the existing 9x19mm and .45 Auto frame platforms.
 
Assault Rifles:

7.62mm x 39mm: a rifle cartridge than tends to tumble in the air causing massive tissue damage to it’s target

5.56mm x 45mm: The 5.56×45mm cartridge with the standard military ball bullet will penetrate approximately 15 to 20 inches (38 to 50 cm) into soft tissue in ideal circumstances. As with all spitzer shaped projectiles it is prone to yaw in soft tissue. However, at impact velocities above roughly 2,500 ft/s (760 m/s), it may yaw and then fragment at the cannelure (the crimping groove around the cylinder of the bullet). These fragments can disperse through flesh and bone, inflicting additional internal injuries

.303 Enfield Mk 7:although the Mark 7 round looks like a conventional full metal jacket bullet, this appearance is deceptive: its designers made the front third of the interior of the Mark 7 bullet initially out of aluminum (from Canada) or tenite (cellulosic plastic), wood pulp or compressed paper, instead of lead. This lighter nose shifted the centre of gravity of the bullet towards the rear, making it tail heavy. Although the bullet was stable in flight due to the gyroscopic forces imposed on it by the rifling of the barrel, it behaved very differently upon hitting the target. As soon as the bullet hit the target and decelerated, its heavier lead base caused it to yaw violently and deform, thereby inflicting more severe gunshot wounds than a standard spitzer design.

5.45x39mm: A smaller version of the 7.62mm x 39mm. It is more accurate with a much higher velocity and only slightly sacrifices the lethality of the larger round.

 
Shotguns:

2 bore loaded with sixty 0000 ("quadruple-ought") buckshot pellets: This gargantuan round is cable of blowing a man in half at the waist at 15 feet with a tight shot. Can only be fired from the RXT- Golem Shotgun. Using a lighter gun may result in serious injury.

8 Gauge Flechette Shell: This shell is loaded with 13 Flechette darts. Used with a tight choke the darts can be lethal up to 150 yards. Capable of light armor penetration. At closer ranges with a loose choke a human with be torn to shreds with a single shot.

10 gauge loaded with Twelve 00 (“double-ought”) buckshot pellets: A standard Military shotgun round during World War III. Effective against combatants at close to medium range with less recoil than the 8 or 2 bore rounds

12 gauge Bolo shells: Bolo rounds are made of four slugs molded onto steel wire. When fired, the slugs separate, pulling the wire taut creating a flying blade, which can decapitate people and animals or amputate limbs. The round is named in reference to bolas, which use two or more weighted balls on a rope to trap cattle or game. Lethal up to 50 feet

3" Nitro Magnum 12 gauge sabot: This aerodynamic projectile is designed to cause more damage than the standard rifle round only with less range in situations where collateral damage is an issue.
