Re: Hand Held Devices With Ballistic Software
The iPhone, believe it, or not, has some terrific ballistics programs available. I'd recommend the full-fledged Bullet Flight program. It does the whole 9 yards.
It provides milrad data, or MOA, and you can calibrate it to the bullet so that the proper number of clicks, depending on the turret step, will be presented based on the bullet, BC (G1 or G7), taking into account spin drift, coriolis, and the iPhone plugs in the local barometric altitude, and temp. You still have to guess the wind, but the iPhone will give you the vertical angle.
Truly an amazing program for $40 (I think). The numbers match very closely those that Bryan Litz provided, free, with the ballistics program that came with his Applied Ballistics for Long Range Shooting book.
Ballistic FTE isn't too bad either.
Pretty amazing stuff.
