Basic Bullet Information

The rounds are all coated in a Tombac full metal jacket and given a slight Molybdenum disulfide coating to ease the movement of the round through the barrel and with loading. While "Teflon" (Really Molybdenum Disulfide) is said to have or give special armor piercing qualities to a bullet, it's purpose more or less decreases friction in the barrel, which consequently decreases barrel wear, and can also increase velocity or accuracy depending on the type of barrel. Because of it's Molybdenum Disulfide coating, all rounds thus appear black, except for their tips (which are left revealed to help signify the type of round). The Molybdenum Disulfide coating is crucial in the fact that is does not wear off or leave behind substantial amounts of residue when fired, and that it can resist temperatures of over 350 degrees Celsius, which similar materials, such as Teflon, cannot. Each round is roughly 12.8 grams and has a spitzer point, with a boat tail to help stabilize the round in flight, as they are intended for long range. The caseless propellant is held together with a Hexagon or RDX binder, which causes the propellant to be far less sensitive then it would otherwise be (reducing the chance of a cook-off tremendously).

The 7mm Remington Magnum is known for being a relatively accurate and powerful cartridge, with an incredibly high ballistic coefficient and resultingly long range. While the casless variant is not identical, it is very similar in performance to the standard 7mm Remington magnum round (although with a dramatically different case shape). Intended as a replacement to the .308 with roughly similar ballistics to the .30-06, the round far exceeds it being more aerodynamic efficient than either, with a BC of .78 in comparison to .5 and .35 for the .30-06 and .308, respectively. Utilizing a round with very similar ballistic shape to the Sierra Matchking 197 grain (12.8 gram) round, with a G1 ballistic coefficient of .78, with a muzzle velocity of 785 to 835 m/s, the round has an incredibly long range, possessing approximately 1,000 joules at 1500 yards, and 500 joules at 2600. At 975 yards, the weapon has more energy than the 5.56mm at the muzzle, with a heavier, larger round, possessing superior armor penetration. While possessing an incredibly long range and a super flat trajectory relative to other rounds, including the .30-06 and .308, the round is designed to compete with the emerging longer range rounds such as the .338 lapua, while being light enough with light enough recoil to still be viable in infantry firearms.




Armor piercing D11
These types of rounds are the basic load, with relatively normal composition and price; they would also be something that a hunter or standard military unit might use. The rounds are essentially Tombac covered Molybdenum Disulfide coated Lead-Steel rounds, with a red tip to signify it's type. The round is basically lead steel and deforms regularly in soft tissue, except for the fact that it has a steel penetrator in the center of the round (unlike the normal rounds, which possess no kinetic energy penetrators). The steel penetrator rarely is exposed when the ordinary lead steel round passes through soft tissue, however, when the round is pressed against a hard target, the lead-steel deforms and "Peels back" which allows the steel penetrator to pass, and carry the kinetic energy of the round into the steel penetrator which is much better at piercing hard targets. This type of round can pierce soft tissue and deliver relatively high amounts of damage, yet when pressed against a hard target they have the ability to penetrate with general ease.

The steel penetrator is essentially 4.1 grams and has a base diameter and shape of a standard 5.56mm x 45mm NATO round. The rest of the lead steel and tombac coating brings the weight of the round to roughly 12.8 grams, or is 8.7 grams. The rounds are similar in style and composition to that of the 5.56mm NATO German D11 round.





"Black Talon" Shredder Rounds
The rounds are essentially based off the Black Talon rounds that Winchester made a while ago. The rounds were of course, extremely deadly and their reputation for being exceptionally deadly produced a wide variety of rumors, many of which were completely opposite to the truth, which lead Winchester to formally discontinue the creation and sale of the rounds. The Shredder rounds are essentially jacketed hollow-point bullets with perforations designed to expand sharp edges upon impact and silicon spitzer points designed to nearly disintegrate upon impact regardless of the hardness of the target (the spitzer point of course, to increase the aerodynamic shape of the bullet). The bullet includes a Molybdenum Disulfide coating, a proprietary oxide process, which gives it an unusual black appearance compared to copper-jacketed or lead bullets. The Molybdenum Disulfide coating was to protect the barrel rifling, and did not give the bullet armor-piercing capabilities. This coating in fact is still widely used on many of Winchester's rifle bullets today. The bullet also had a unique appearance with a star shaped perforation on the black tip, giving it the nickname Starpoint. The internal structure of the Black Talon’s hollow point is unique in that its petals are more massive at their tips, after expansion, than comparable bullets. This added mass provides superior expansion compared to most other hollow points including the “Ranger SXT”.

The Five Star petal shapes of the Black Talon Shredder rounds essentially translate into superior expansion and very controlled expansion in most soft tissue materials, allowing for a greatly increased, reliable soft targets. In particular, the rounds usual ability to penetrate basically translates into greater expansion, with the energy spent on penetration translating into greater expansion and less penetration. Even so, the extreme power of the round typically results in over-penetration in most soft targets. The rounds are similar in shape to many sniper bullets for the 7mm Remington magnum, being a boat-tail hollowpoint which gives the weapon significantly greater aerodynamic efficiency.






High Explosive Incendiary Armor Piercing Rounds (HEIAP)


High Explosive Incendiary/Armor Piercing Ammunition (HEIAP) is a form of shell which combines both an armor piercing capability and a high explosive effect. In this respect it is a modern version of armor piercing shell. The ammunition may also be called Semi-armor piercing high explosive incendiary (SAPHEI). Typical of a modern HEIAP shell is the NM142 MP Mk 208 Mod 1 round designed for weapons such as heavy machine guns and anti-materiel rifles.

The primary purpose of these munitions is armor penetration, but unlike SLAP rounds (Saboted Light Armor Penetrator) which get their armor piercing ability from the propulsion of a 5.56mm tungsten heavy alloy bullet from a 7.62mm barrel using a sabot with much more energy than is usually possible from a 5.56mm round, HEIAP munitions use high explosives to "blast a path" for the penetrator. The special effect is developed when the round strikes the target. The initial collision ignites the incendiary material in the tip, triggering the detonation of the HE charge. The second (zirconium powder) incendiary charge will also ignite. This burns at a very high temperature, is not easily extinguished, and can last for 30 seconds.

The remaining element of the round is the tungsten carbide penetrator. This has a large amount of kinetic energy and will penetrate the armor as solid-cored armor piercing shot would. This will take some of the incendiary material through the armor. The MK 211 is claimed to penetrate up to an inch (25.4mm) of rolled homogeneous armor. The triggering of the explosive charge is dependent upon the resistance of the target. If the target offers little resistance then the lack of frictional heating will prevent the incendiary from igniting and the high explosive from detonating. Larger guns such as the British 30 mm RARDEN cannon fire APSE (Armour Piercing Special Effects) shells which are an armor piercing round with added HE effect.

This round is usually identified by a green over white paint tip mark. A rarer occurrence of a green–over red–over white paint mark scheme indicate the tracer version of this round. These tracer versions are usually only seen on cartridge feed belts in naval applications. The headstamp on the casing can also help to identify the round as Raufoss and some common headstamps include, but not limited to: HXP89, WCC94, and FN91; or HXP, WCC, LC, or FN with different two-digit numbers as production year suffixes.

The round itself is essentially a 12.8 gram container, and has roughly the same proportions of materials as the Raufoss Mk 211 cartridge. The round is not entirely velocity dependent, relying on high explosive and incendiary materials for much of it's effects. The incendiary material is used to detonate the explosive RDX, and as a result not detonater is required, which drastically simplifies the round's mechanism, but requires that the round's target possesses enough hardness to detonate the round. The ratios of materials, in weight, is 3 grams for the C-4, 3 grams for the cubic zirconium, 2 grams for the incendiary mix detonator, 2 grams for the lead steel, and 3 grams for the tungsten carbide penetrator.
