    Question 4.6x30mm v 5.7x28mm Ammunition

    Here are a few small calibre rounds I have in my collection.

    Round 1
    Case: Brass
    Calibre: 5.56x45mm .223
    Headstamp: HP 80 II
    Manufacturer: Hirtenberger Austria
    Year: Q2 1980
    Weapon: M16, SA80

    Round 2
    Case: Steel
    Calibre: 5.45x39mm
    Headstamp: 270 88
    Manufacturer: Lugansk Ammo Factory, Ukraine
    Year: 1988
    Weapon: Russian AK 74 Series

    Round 3
    Case: Brass
    Calibre: 5.7x28mm
    Headstamp: FNB 90 5.7x28
    Manufacturer: Fabrique Nationale Herstal, Belgium
    Year: 1990
    Weapon: PDW (Personal Defence Weapons), FN 5-7N pistol, FN's P90 SMG

    Round 4
    Case: Brass
    Calibre: 4.6x30mm
    Headstamp: RG 05 4.6x30
    Manufacturer: Radway Green, UK
    Year: 2005
    Weapon: H&K MP7 (Heckler & Koch)


    Round 5
    Calibre: .17 HMR

    Round 6
    Calibre: .22 LR

    Who manufactures Round 1, can anybody identify Round 2? What do we know about Round 3 & 4 which I think are the most interesting and what are RG producing 4.6x30mm ammunition for? Can anybody tell me the history of these rounds? Rounds 5 & 6 are only there to show size differences.

    What is the best online headstamp guide?

    No 1 is a 5,56x45 or .223 made by Hirtenberger Austria ( HP ) in the second Quarter 1980.
    No 2 is a 5,45x39 Russian used in the AK 74 series weapons and 270 is the factory code for Lugansk Ammo Factory in Lugansk - now Ukraine 88 is the year.

    RG etc.

    To answer a couple of your questions.

    SMLE (Tony) has already given a fairly good description of the FN 5.7mm. This and the 4.6mm are both for what are called Personal Defence Weapons, and are designed to replace the 9mm in both pistol and submachine gun roles. The theory is that it will be more effective and easier to use that a pistol or SMG.The main criteria is that it should be capable of penetrating body armour at reasonable ranges, something the 9mm cannot do.

    Having said that, they have not be taken up with any great enthusiasm by any major army. I believe the Saudis have bought some P90s but it has not been successful to date. Tony Williams is far better qualified to give you an update on this than I am.

    Why are RG making the 4.6mm? It dates back to when both Radway Green and Heckler & Koch were co-owned. The ammunition was developed by RG and the MP7 that fired it by H & K.

    Currently the MP7 is used by the MoD Police in the UK and a number of other police forces have it on trial. The logic is that it will be more capable than the 9mm in the MP5 if confronted by terrorists in body armour.

    RG make a range of loads for the 4.6mm, including solid copper, spoon tip (two different types) as well as conventional bullets.

    Attached is an RG made drill round as an example.

    Regards
    TonyE
