The sheer resources and artifice skill required to craft these weapons is extraordinary, and as such they could not be mass-produced to arm the Space Marine Legions during the Great Crusade. These shells are uncommonly dense, requiring a far stronger charge to launch than standard bolts, and only the Lastrum Storm Bolter's uniquely sturdy construction for a weapon of its size can withstand the stress of repeated firing. Once within their target, these burst into brief, but sun-hot incendiary detonations, incinerating their victims from within. Rather than the usual Kraken bolts utilised by the Legio Custodes, the artisans of the Lastrum clans hand-manufacture only customised mass-reactive heliothermic warheads for their bolt shells. Other than being exemplars of their kind in terms of skill of fabrication, they would not be remarkable save for their uniquely powerful ammunition.

Lastrum Storm Bolter - The Lastrum Storm Bolter is named for the weaponsmiths of the Lastrum Core Clan of the Appolyne workshops of Terra.

Known Storm Bolter Patterns Adeptus Astartes Patterns They are now only used by the Chaos Space Marines of the Traitor Legions, many of whom still have access only to the pre-Heresy technology. These were called ' Combi-Bolters' and they were less effective than the first true Storm Bolter design. These bolts are identical to those fired from Bolt Pistols and bolters.Д«efore the Storm Bolter was created by the Tech-priests of the Adeptus Mechanicus after the end of the Horus Heresy, Terminators were often equipped with two separate bolters outfitted with advanced targeting equipment and restricted firing rates to allow them to operate in tandem. Storm Bolter, Mark IV Thunderfury PatternДue to its high munitions consumption, and the lack of dexterity available to the wearer of Terminator Armour, most Storm Bolters are fed from a large box magazine, carrying approximately 100 bolts. The Storm Bolter also sees limited use amongst the Orders Militant of the Adepta Sororitas, where it is considered a specialist weapon, and favoured by those squads of Dominions, the Sororitas' heavy-weapons troops, who prefer to engage in mid-range, anti-infantry combat.

Storm Bolters are also used by the Astartes of the Grey Knights Chapter as a gauntlet-mounted weapon with its feed located on the rear of their armour. Instead, Storm Bolters are the standard weapons employed by Space Marine Terminators or as a pintle-mounted weapon on an Imperial main battle tank. As it is heavier and causes more recoil than a normal bolter, it is even more rarely used than the bolter by the regiments of the Astra Militarum. The Storm Bolter is a double-barrelled version of the standard.
