Why are the cannons so weak on the 109-E, yet so strong on the Russian planes?

Good info Steyr, rate of fire must have some influence on hitting a moving object, whether it is a human being or a fighter plane, that is probably why a machine gun was created in the first place, more bullets can make up for a lack of accuracy…as will most likely happen in a moving plane. There may be some differences in rpm, velocity and projectile mass, and with equal pilots in two different planes, one may have a slight advantage, but really, in the end, as Winny says, it may all come down to Luck!
