List of 40 mm grenades
cartridge
This is a general collection of the world's many types of ammunition for grenade launchers in 40 mm (1.57 in) caliber.
Several countries have developed or adopted 40 mm-caliber grenade launchers.
NATO
NATO currently uses three standardized 40 mm grenade families: 40 mm low-velocity (LV), 40 mm medium-velocity (MV), and 40 mm high-velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers.
40×46 mm LV (40 mm low velocity)
40×46 mm LV (low velocity) is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, Heckler & Koch AG36 and M320 Grenade Launcher Module.
The propellant has low pressure and gives the projectile an average velocity of 78–84 m/s (256–276 ft/s) depending on the ammunition type.
40 mm low-velocity ammunition types (NATO)
Besides combat ammo, there is also crowd-control ammunition such as sponge grenades.
40 mm low-velocity ammunition types (Sweden)
Sweden currently operates the M203 grenade launcher (designated Granattillsats 40 mm Automatkarbin in Sweden) and thus uses the 40 mm low-velocity cartridge. Going against Swedish military tradition, the 40 mm low-velocity cartridge currently lacks a specified indigenous designation in Swedish service. Instead only the projectile types have designations.
This brief starts where responsible research should: with the source description of “List of 40 mm grenades” as cartridge. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as cartridge. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q231328. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
