it is apples and oranges to me. I've made my argument about the weight of the machine guns, which like i said before, was extraneous, when considering the reliability of the .50 cals vs the 20mm tendency to jam.
"Better range" meaning, they could shoot a burst in front of a target and the plane would fly through a stream of bullets.
It would be very wasteful to use cannons in that manner, so it often required a closer shot, and many times wasn't the choice weapon for air to air combat, until later in the war when fire rates and reliability had improved.
You can go on and on about the weight, but it s extranious to mention the weight considering the obvious benefit of having a large ammo supply and the ability to fire at 800rpm. Cannons didn't reach this fire rate until later in the war when, you started to see them on F4s.....
(I don't actually think there was a worthwhile difference in trajectories between the 12.7 mm Browning and the 20 mm Hispano II, by the way.)
It is a notable difference as the 20mm began to fall away from its target and had a greater arc when firing in turns, primarily because of the weight of the shell.
i feel like i'm repeating myself.![Laughing :lol: :lol:](/forum/images/smilies/icon_lol.gif)
