Remarks

Since the burn duration of both the Serbian shrapnel differed from that of the Bulgarian ones, the following corrections must be applied to achieve normal bursts:

a)    with Bulgarian Schneider field guns:

53 firing at 1000 m

58 firing at 2000 m

60 firing at 3000 m

66 firing at 4000 m

70 firing at 5000 m

74 firing at 5500 m

b)    with the Turkish 75mm Krupp field gun:

59 firing at 2000 m

c)    with Brazilian 75mm Krupp field gun and Serbian Schneider field gun:

H.E.Shell

Fuze:

 

Shell:

6.5 kg

Colour:

The body and the ogive are yellow

Remarks :

The text describing the use of captured Serbian ammunition states that this shell is identical to the Bulgarian one and functions in the same way; however, I have been unable to identify it, as Bulgaria used only German high-explosive shells, and it is unlikely that Serbia had them.

Propelling charge

570/580 g of tubular or taped pyroxiylin powder

Cartridge case

Casings and primers were identical to those of the Bulgarian Schneider model.

Shell:

5.3 / 5.45 kg – 800 g of Melinite

Remarks:

Firing with Bulgarian field guns of every model, the muzzle velocity of this shell is 525 m/s

Obus à balles

Fuze:

Fusée à double effet 22/31 (French T&P fuze graduated up to 24’ = 6200 m)

Shell:

Modified Serbian shrapnel

(long type)

Fuze:

Shell:

6.870 kg – ? bullets x 10 gr, 80 g of black powder

Modified Serbian shrapnel

(short type)

Fuze:

Fusée à double effet 22/31 (French T&P fuze graduated up to 24’ = 6200 m)

Shell:

6.700 kg – ? bullets x 10 gr, 80 g of black powder

Colour:

The body and the ogive are red with a blue ring on the driving band

Remarks:

Shrapnel equipped with French fuze can only be set using the French fuze setter, which differs from the standard Schneider model; if this is not available, fuze-setting pliers must be used.

The French H.E.shells are 5 mm longer than the Bulgarian ones; consequently, the lid of the ammunition wagon can be closed – albeit with great effort – whereas the shrapnel, being significantly longer, make it impossible to close the the lid.

French ammunition for the Greek Army

Armour piercing H.E. shell

Fuze:

Fusée de 24/31 (French percussion fuze)

Shell:

4.9 kg – ? g of Trotyl

Colour:

 

Remarks:

Handed over by the Greeks to the Serbian Army.

Firing with Bulgarian field guns of every model, the muzzle velocity of this shell is 540 m/s.

Propelling charge

600 g of powder B.S.P 

Cartridge case

Externally, French shell casings resemble Bulgarian ones; however, their base and the surrounding rim are thinner, the screw primer is smaller, and the black powder ignition charge is contained within a long, thin tube that protrudes from the base of the casing. With Serbian or Bulgarian guns, to ensure that the base of a French casing adhere to the breech-block, some casings has a brass ring soldered to the rim, while others are fitted with a looped cord. Cartridges with casings that with the looped cord must not be used with Krupp guns, because in such cases the breech-block cannot be closed.
