Rate of fire is quite interesting topic because there were a lot of discussion on WW2 or games forums about 0.5 cals gun's RPM (Browning, Breda, Ho-103), which fire through propeller. One guy (greybeard) summarize his research and made mod for IL2 1946:

More about problem of a significant RPM drop after synchronization with propeller here:
https://quarryhs.co.uk/Synchro.pdf
Citation from this document: "Some installations appeared to be even worse than this; tests of cowling-mounted .50 M2 in US aircraft revealed RoFs of 400–450 rpm, and anecdotal reports of the Japanese 12.7 mm Ho-103 (which shared the M2's Browning short-recoil mechanism) indicate a similar problem."
In conclusion synchronized Breda Safat propably had better RoF than synchronized Browning guns. Additionally for Bredas we can easily find information that RPM was about 570 if they were synchronized.
0,8 g PETN (filler of HE bullet, 1.3 g TNT equivalent) was good or bad we don't know, because we don't have any reliable reports about that. I was able only to find this pilot description of damage after fight with Italian fighters euipped with 12.7 mm

If they were producing HE bullets after tests I can only assume that they were decent bullets and they were making significant damage to take down enemy aircrafts.
For me main disadvantage of Bredas is that shells faster drops their speed. With Brownings aiming is much easier. BREDA's relatively low muzzle velocity and bullet's weight are fact. But we can't definitely claim that their bullets inflicted less damage or in case of synchronization with propeller their RPM were worse than "contemporaries" (Browning, Ho-103).
Is there any stat-card or something about guns and ammunition in this game? Muzzle velocity on distance, RPM (synchornized, unsynchronized), penetration on distance etc.
