For those who are interested in prefecting their air to air gunnery skills using the Spitfire with the reflector gunsight, the link below will take you to a very good explaination of the gunsight, how it works and how to use it. This may be a repeat for some as I'm sure it can be found elsewhere in this forum, but for those particularily interested in Spitfire resources, I'll add it again. The Tides of War/Cliffs of Dover post below includes a summary of the typical wingspans of all your favorite playmates.

I did some simple math, being Christmas leave what else would I be doing?
Set your gun convergence according to your preference (remember to convert the convergence setting which is in meters, to yards to match the gun sight). If you set your gun convergence to 100 yards (x .9144 = 91.44 meters), then considering that the British .303 Mk VII at 174 grains with a muzzle velocity of 2,440 FPS takes .12 seconds to travel that distance, your application of lead in a turning fight where airspeeds drop to about 250 MPH, a Bf 109 with a length of 29' 4" and wingspan of 32' 6' will travel about 44' in .12 seconds. So your lead should be about 1.5 x lengths at that speed. Then consider angles of attack (to compensate for ballistic drop), rates of closure or separation and you should be on target with some practice.
