I have a feeling they also had a lower muzzle velocity, but not sure about that one. Sorry for being such a thicko.
right, let's do some maths together...

the .303 had a blistering 20 rounds per second, the synchronised MG17 shot 17, frankly not that much of a difference, especially cos the .303 bullet weight was around 10 grams and the 7.92 is 11.5 grams, but the MG/FF (in its AP format) had a poor 8 rounds per second, but was a blistering 117 grams with 3.5 grams of explosive.

Now let's look at the damage factors*: both the MG17 and .303 had an average damage factor of 10, while the MG/FF went from 90 of an AP to a staggering 206 of an HE. This is again for one round.

so (and again this is a theory that doesn't take external factors into account) 8 .303s would deliver at their convergence point 160 bullets in a second, for a total damage factor of 1600; 2 MG17 would deliver 32 bullets and a damage factor of 340; 2 MG/FF would deliver 16 rounds with a damage factor of 1440 (the HE would reach a blistering 3296).

So all in all we're there (unless we use HE), but in terms of efficiency per single round, it's quite obvious that one MG/FF round would cause enough damage, being the most efficient of the lot.

The Dowding spread was soon chucked out of the window, but has no relevance to Holland's blatant exaggeration of the 109's firepower.
How soon exactly?

I say again, 55 seconds of cannon fire? Is that a fact, or just propaganda? Not confusing anything here mate. Poppycock and balderdash Old Boy.
I believe he referred to total firepower, and in terms of destructive power the 7 secs of MG/FF were surely comparable to 55 secs of .303s.

Ah so you're implying I'm a charlatan? Funny that, we lot living on Planet Reality Check thought that the charlatans were you and your esteemed colleagues coming from Planet I Fill My Mouth With Nationalistic Ideas And Never Open A Book On The Subject, go figure
