I don't know what you're asking. What's the trouble?

Aim the centre according to how far away your opponent is...if he is far, aim above, if he is clse, aim for his ***! Thats how i do it.

The seris of rings and lines on this sight
are used to calculated the amount of leed
you give to hit your target. So when you engage
a target at low angle or low speed you adjust
your leed from center of the sight to the inner circle of the sight.If the target is at high speed or high angle you adjust the leed from
center of the sight to outer ring on the sight.
The vertictle tck marks gives you the mils of
deflection by 10mils each tick up 100mils.

I was going to ask what a mil was, but I looked it up.

<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content">
mil [1]
a unit of distance equal to 0.001 inch: a "milli-inch," in other words. Mils are used, primarily in the U.S., to express small distances and tolerances in engineering work. One mil is exactly 25.4 microns, just as one inch is exactly 25.4 millimeters. In Britain this unit is usually called the thou.

mil [2]
a unit of angle measure, used in the military for artillery settings. During World War II the U. S. Army often used a mil equal to 1/1000 of a right angle, 0.1 grad, 0.09â?, or 5.4 arcminutes (often written 5.4 moa; see "moa" below). More recently, various NATO armies have used a mil equal to 1/1600 right angle, or 0.05625â? (3.375 moa). In target shooting, the mil is often understood to mean 0.001 radian or 1 milliradian, which is about 0.0573â? or 3.43775 moa. In Britain, the term angular mil generally refers to the milliradian. 1 milliradian corresponds to a target size of 10 millimeters at a range of 10 meters, or 3.6 inches at 100 yards.

I guess it's left a bit vague but means a small distance or a small angle. That doesn't seem very helpful does it?

the circles are for measuring distance - an aircraft wings will touch the outer circle when it is 100m away. It will take 2* wings at 200m away. this prevents you from firing when bandit is out of range,
They also help to measure lead- how much in front of an aircraft you have to fire to allow for the bullets to match the distance the bandit travels. The lines are to help you match the angle of bank of the bandit.

Here is a guide to shooting with links to other information-

http://www.airwarfare.com/guides/snapshot.htm

there is specific training as given to USN pilots using this sight, Ill try to remember the site and post back but I prefer using Andy Bushs guides which are linked in the snapshot guide.

edit - here are the old guides- they discuss mils etc for this sight

this is the navy's mark-5 gunsight. extremely accurate once u understand it. lets look at the pic above at a different angle. situation: bandit breaking at a 90 degree angle. what i do is, i put the angled bars along the bottom of his fusalage. say he was turning right. i'd use the right hand angle, and put it on the bottom of his fusalage. he'll get torn up real quick.

this sight is about as accurate as the p-51's gyro sight, only this doesnt float like the gyro's tho.

Most of the times I aim at plane with center of the crosshair. That goes for all .50cal armed planes.
The exception is deflection, which is by far easiest on K14 P-51.

The RAF Gunnery Guide gives the best explanation of how to hit moving targets.

I can't find a link though (anyone?).
