Here is a bunch of stuff on the RPG ammo from Janes. I do not know if this helps any. And it is long. Who knew that there were so many warheads. Some estimates on RPG-7 production is over 9 million!
Ammunition
The grenade is a two-part unit. The overbore warhead and rocket motor comprise the forward end, and a shorter rocket motor which acts as a launcher for the complete unit is secured to the warhead/rocket motor base by a large threaded projection. On firing, the grenade is propelled from the launcher, and after it travels approximately 10 m, the main rocket motor fires, and the velocity is increased. The launcher unit has four aluminium fins which unfold, and, aided by small offset fins at the rear, a slow roll is imparted to the rocket to aid stability. At the rear end of the missile are small offset fins that give a slow rate of roll to improve stability. The point at which the main rocket motor cuts in is consistent and is a major factor in obtaining round-to-round matching of trajectory.
Details of the grenades fired by the RPG-7 series - which now include warheads of the tandem-warhead, anti-personnel and thermobaric types - are as follows:
PG-7 grenade
The PG-7 grenade, the original grenade used with the RPG-7, has a warhead cone diameter of 73 mm and a fluted nosecone cover. A more recent warhead, designated PG-7M, has a cone diameter of 70 mm, but, through better design of the fuzing and firing arrangements, it has a better anti-armour performance. The PG-7 grenade fuze is a VP-7M Point-Initiating Base-Detonating (PIBD) type, using a piezoelectric head connected to the actual fuze in the base of the shaped charge. Early versions of this fuze were prone to malfunction if the fuze were short-circuited by external contact, so screening a target with wire mesh gave a high probability of shorting out the piezoelectric unit and thus rendering the fuze and the warhead inert. Later versions of the fuze corrected this defect. The updated warhead has a slightly longer nosecone so appears to be slimmer. The muzzle velocity of the PG-7M round is 140 m/s, the length is 950 mm and the weight is 1.98 kg. The complete round with the PG-7 grenade is the PG-7V. That for the PG-7M is the PG-7VM, produced in Poland as the PG-7WM.
GTB-7VS1 grenade
This thermobaric round is designed to defeat brick and concrete fortifications, light armoured vehicles and troops in the open. The direct-fire range is given as 150 m, and the maximum range is given as 800m
OG-7VMZ grenade
The OG-7VMZ is an anti-personnel grenade fitted with the O-4M fuze. The direct-fire range is given as 165 m, and the maximum range is given as 1,000 m.
PG-7N grenade
The PG-7N is basically an updated PG-7M with a revised warhead containing 340 g of Okfol-3.5 initiated by a VP-22 piezoelectric fuze. Also revised is the 4RN42 propelling charge, which provides an initial velocity of 140 m/s and a maximum range of 500 m. The length overall is 965 mm. Armour penetration is given as 400 mm. The complete round is the PG-7VN.
PG-7L grenade
The PG-7L grenade has a 93 mm diameter shaped-charge warhead capable of penetrating 600 mm of armour. The grenade weighs 2.6 kg and is effective up to 300 m. The muzzle velocity is 112 m/s. The grenade can also penetrate up to 1.3 m of reinforced concrete, 1.7 m of brick and over 2.5 m thicknesses of logs and earth. The complete round is the PG-7VL.
PG-7LT grenade
The PG-7LT is produced in Bulgaria and is another tandem-warhead grenade, with a weight of 2.9 kg and a length of 1.13 m; the main warhead diameter is 93 mm. The maximum effective range is 300 m at a muzzle velocity of 100 m/s. It is provided with a VP-22 impact fuze. It is claimed that this grenade will penetrate 550 mm of armour once Explosive Reactive Armour (ERA) has been cleared, or 700 mm of armour with a behind-armour effect. It can also penetrate 1.4 m of reinforced concrete or brick, or 2 m of logs and earth. The complete round is the PG-7VLT.
PG-7VM grenade
This is a Romanian High-Explosive Anti-Tank (HEAT) round with a 70 mm diameter warhead, produced by RomArm. A complete round is 959 mm long, with the grenade being 671 mm. The maximum firing range is 500 m, and the maximum velocity is 350 m/s. The warhead can penetrate 300 mm of armoured plates at 330 m.
PG-7VR grenade
The PG-7VR round is fitted with a tandem warhead to attack ERA, having an extension boom ahead of the main warhead carrying a small shaped charge to ignite the ERA before the main 105 mm diameter shaped charge operates to penetrate the main armour. The complete PG-7VR round weighs 4.5 kg and has a maximum effective range of 200 m. It is claimed that the PG-7VR grenade can defeat the passive and active armour of all current main battle tanks, being capable of penetrating more than 750 mm of armoured steel after defeating ERA. It can also penetrate over 1.5 m of reinforced concrete, 2 m of bricks and up to 3.7 m thicknesses of logs and earth. This warhead was deployed during the 1995 fighting in Chechnya.
PG-7LT grenade
The PG-7LT is another tandem-warhead grenade to defeat ERA. The complete round, the PG-7VLT, weighs 2.9 kg and is 1.13 m long. The maximum warhead diameter is 93 mm. The muzzle velocity is 100 m/s, and the direct-fire range is 200 m. The PG-7LT grenade can penetrate 700 mm of Rolled Homogeneous Armour (RHA), with behind-armour effects, or 550 mm of RHA after one layer of ERA. It can also penetrate 1.4 m of reinforced concrete or brick and 2 m of logs and earth.
PG-7M 110 grenade
The PG-7M 110 is a Slovakian enhancement; see separate entry.
PG-7 T 110 grenade
Dezamet of Poland and Dynamit Nobel (later Dynamit Nobel Defence) of Germany entered into a joint programme to integrate the Panzerfaust tandem warhead with the Eastern-bloc PG-7. This combination is known as the PG-7 T 110. Initial static and firing tests were carried out in Poland in May 2000. For details of the Panzerfaust warhead involved, see separate entry.
PGI rocket
The PGI is a rocket with an incendiary 70 mm diameter warhead produced by RomArm of Romania. The maximum firing range is 500 m.
PG-I incendiary round
This is a Romanian incendiary round with a 70 mm diameter warhead, produced by RomArm. A complete round is 959 mm long, with the grenade being 671 mm. The maximum firing range is 500 m with a maximum velocity of 350 m/s.
Kodori-3 and Kodori-4 rockets
These are Georgian anti-personnel rockets with High-Explosive Fragmentation (HE-frag) warheads; see separate entry.

PUS-7 training device
The PUS-7 is a training device firing 7.62 × 54 mm R ammunition. The PUS-7 outwardly resembles a PG-7 rocket and is loaded into the RPG-7 launcher and fired in the same manner as an operation round. After firing, the PUS-7 is removed and replaced by a fresh training round. The device is reloadable. Training ranges are up to 300 m for mobile targets and 400 m for static targets. The PUS-7 is manufactured by Arsenal of Kazanlak, Bulgaria.
In addition to the above grenades, the RPG-7 series can also use the Chinese Norinco 40 mm grenades intended for the Type 69-1 launcher. For other RPG-7 launcher and ammunition suppliers, refer to the list of similar-model manufacturers below, although it should be borne in mind that RPG-7s and their associated rocket grenades have been manufactured by an increasing number of non-former Soviet-bloc countries.
