Breda Vs Berezin

[F/JG300_Gruber]

I just noticed something yesterday,

 

 

When shooting with the Mig and it's berezin UB machinegun, I'm getting puffs of smoke on a regular pattern indicating AFAIK explosive bullets in the belts :

 

 

However I never get this effect with the Breda SAFAT of the MC202 :

 

 

So far I believed that explosive 12.7mm was an Italian specificity  (but I can't find anything about UB ammo belts)

 

 

I intend to submit a bug report but I would like to know first if the Mig incorrectly gets explosive ammo for it's 12.7mm and the Macchi doesn't, or if the Berezins are correct and it's just the explosive effect missing on the Bredas.

Not sure about the Bredas, but they did use HE ammo on the UB.

[=362nd_FS=Hiromachi]

Italian 12.7 mm Breda-SAFAT used HE ammunition, it contained 0.8 g of PETN if I'm not mistaken. Or RDX. Cant be sure now. It also had a decent load of incendiary component, I believe it was Potassium Perchlorate. 

 

Soviets had whole series of 12.7 mm HE rounds, beginning with MD high explosive produced since 1940:

The MD-46 and MDZ-46 bullets were high explosive bullet designs from early WWII and a number of specimens from that time exist. Inside the gilding metal clad steel envelope a steel body filled with high explosive is located. The MDZ-46 bullet differs from the MD-46 in having an additional incendiary filler below the high explosive payload. The high explosive incendiary bullet MDZ-3 ignites gasoline in unprotected fuel tanks only. When fired into a duralumin aircraft wing, the MDZ-3 bullet creates an entrance opening with a diameter of approximately 20mm and an exit opening of up to 110mm diameter. The modern MDZ bullet defeats a 2.0mm duralumin sheet at a range of up to 1,500m.

 

Overall, Soviet HE round is by design and capabilities more effective than Italian round, which might explain the effect. When I usually shoot with my Mc 202 I see small flashes around areas hit, but no "puffs" like mentioned.

Thanks for the precisions !

 

Indeed, 2.1g of PETN is a lot more than the Italian design !

 

For the flashes, I get the same kind with any 7.x caliber bullets, so I'll see if we can have a special effect for the Bredas (like a smaller puff than the UB)

Might also help in learning shooting these guns
