Algebreic formula for ballistic charts?

[Tim K]

If you happen to have an iPhone or iTouch, get this app. It has all the variables accounted for and, as far as I can confirm in the field, predicts bullet paths with remarkable accuracy. It factors in air density (barometric pressure, altitude, temp, humidity), wind speed and direction, muzzle velocity, etc., etc. It will even account for Coriolis effect (the earth spinning under your bullet while it's in flight). Pretty cool.

This is exactly what I was going to post. This is the best online ballistics calculator site I've found, and is what I use. I've even used this to try to get an idea of what a prospective load will do, and it's great for coming up with range cards for loads I like. I've used it to help make decisions on what calibers/cartridges I want for certain applications as well.
