Reverse ballistic calculator ?

[Niko-PG]

Is there such a thing ?
Let's say I input my bullet data, my come-up all the way to 500m, the weather and it will give me my speed, data to 950m etc...

Limited application I know, but I could use this right now

You could try just using a regular ballistic calculator and change the muzzle velocity to get the drops you experienced in the field.

You could then determine your drops to longer ranges based on that muzzle velocity.

The Nightforce Ballistics program has this feature. Based on your initial come-ups, bullet data and atmospheric conditions it calculates the speed of your bullet, which in turn you can use to finish your bullet drop chart.
