The unique MP design exclude the use of a complex expensive fuze because the need for detonators and sensitive high explosives have been eliminated. Earlier use of different ammunition types (HE, HEI, AP, API, APHEI, etc.) can now be replaced by one type namely the MP concept. The multipurpose (MP) ammunition has been developed to cover a wide range of targets which results in easier logistic handling. In angles between 45 and 85 degrees the projectile will ignite dural plates with thickness down to 1mm. The projectile will ignite after hitting a 2mm dural plate in angles of impact between 0 to 85 degrees NATO. The fragments will have an increase in velocity of about 10–15 percent, due to the blast pressure. These fragments have the energy to penetrate a 1.25mm steel plate 2 meters behind the impact plate. The MP projectile produces about 20 fragments and delivers them in a 25–30 degree cone inside the target. To illustrate the fragmentation effect and pattern, ammunition makers often use a sandwich target. That “area suppression effect” is the one that has induced most erroneous perceptions about the MP bullet, helped by various combat videos, in which the fragmentation cone effect of the MP round is described. It was optimized for an anti-vehicle role with a secondary role against light armor and area suppression. The MP round delivers fragments, blast and incendiary effect after penetrating light targets. The ammunition functions via a pyrotechnical ignition train with delayed action of the blast, large fragments and incendiary effect inside the target. The MP ammunition is designed to defeat targets like airplanes, helicopters, trucks, APCs (armoured personnel carriers), IFVs (infantry fighting vehicles) and other material targets of non-armoured or semi-armoured character. This is well regarded due to its renowned high performance capabilities and excellent safety characteristics. The unique, Nammo Raufoss developed Multipurpose concept has been applied to a wide range of products. Also, the MK211 will not ignite if hit with force, subjected to shock, dropped, vibrated, handled roughly, put away for long storage, submitted to above average temperatures or electronically pulsed. It does not have any primary explosives so is pretty safe to use. The projectile won't do anything even when crushed but still needs a bigger clearance in order to manufacture it. The round will function reliably when hitting the target. The ammunition is drop safe from more than 15 m, and is completely safe to handle after the drop and can be fired from the gun without any safety risk. The Multipurpose Concept is safe in transport, storage and handling. It is used in a 1-5 ratio through the M2 browning. The tracer variant of the MK211 is called the MK300. The MK 211 is claimed to penetrate from one (25mm) up to a possibly apocryphal claim of two inches (50mm - though this could be at the muzzle) of rolled homogeneous armor - though it is mainly made for anti-material and anti-vehicle roles, not anti-armor. It can also be used for anti-explosive, anti-material, anti-vehicle and impressive suppressive fire, especially in urban areas. It also says that the US Army Snipers use this the vast majority of the time while training - it is pretty much the only round they use.It is a multi-purpose round that can be used on both soft (human targets and alike) and hard (apc, pick-up truck targets and alike) targets - making it a deadly round to be reckoned with. 50 caliber round on the planet but this is inaccurate as other rounds and hand loaded rounds can be more accurate. Plaster (MACV-SOG, Ret) and his book says that it is the most accurate. The MK211 round is recommended by John L. The 12.7mm multipurpose concept was introduced in 1981 with a design focused on penetration, fragmentation, incendiary and blast effect. Nammo Raufoss AS holds all patents rights on the concept. This multipurpose concept was developed in the late 1960s based on requirements from the Norwegian Defence Forces for a more cost effective ammunition for use in 20mm airborne guns and airdefence guns.
