Wind from different directions:

Wind head on, or at your back doesn't count.
Wind from left or right is full strength.

Wind at 45° isn't 50%, it is 75%. So smaller angles have more effect than you might think.

Lee Enfield, smaller groups at longer ranges.

Some Lee Enfield target shooting is/was done with free floated barrels. As the bullet leaves the barrel, the barrel is on the upswing of its vibration. If some of the bullets are at a lower velocity, the leave the barrel later, and at a steeper angle. At 600 yards, the lower velocity would cause the bullet to strike lower. But the higher angle on the twanging barrel raises the bullet strike to compensate exactly. So stringing due to velocity variation is gone.
In effect, the rifle varies its zero according to the velocity:

The problem is that at the halfway point the variable zero is exaggerating the velocity difference. "There is no such reality as something for nothing".
So the low velocity barrel twang raises the trajectory just right at 600 yards, but way too much at 300 yards.
Windage is not affected, although bad bedding can cause the effects below:

I used Google Presentations for this, it isn't bad.

GunSim Ballistics Key Facts Mailing list

And now for something completely different. Almost. The GunSim Ballistics Key Facts Mailing list. This means you get a short email with key facts about ballistics each week for a few weeks.
It adds up to a little mini-book on with a condensed overview of ballistics  as applied to shooting.

Ballistics for Linux

Here are some screenshots of the Linux Ballistics Program. I like the Open Source movement, the tools needed for the program's development were free.
