Well i was plowing through some books and Websites looking for data on the H0-103 and Ho-5 and i was looking at the data for the ShVAK and well WOW. Maybe i missed something but color me thick is this the gun we have in AH, i mean is it modeled to preform like these figures indicate?
The 20mm ShVAK cannon was introduced to service in 1936 as armament for aircraft. The Shpitalny-Vladimirnov Aviatcionnaya Krupnokalibernaya cannon was gas-operated and 1760mm or 2210mm long, its rate of fire was 800rpm, its weight 42kg or 56kg. The ShVAK cannon had certain similarities to the Hispano-Suiza cannon HS 404, it had a 1245mm or 1700mm long barrel.
In 1945, the improved Berezin design B-20 aircraft cannon in this caliber was introduced, it had the same rate of fire but it weighted only 25kg and was much more reliable. The gas operated cannon could be mounted in wings and turrets, after WWII it was mounted as PV-20 defensive cannon in turrets of heavy bombers.
OZ HEI 75,3 770 Nose fuze, 2,8g HE + 3,3g incediary

OFZ HEI-Frag. 68,3 790 Nose fuze, 0,8g HE + 3,8g incediary, fragmentation grooves on shell
BZ API-HC 96,0 750 Mild steel shell with hard core, surrounded by 2,5g incendiary, screwed on aluminum or bakelite ballistic cap
BZ API 96,0 750 Solid steel shot with incendiary in swaged steel cap
BZT APIT 96,0 750 As above but with tracer in base cavity
PU TP 68,3 790 Inert filled HEI shell with dummy fuze
