Here is another web based ballistics calculator with some nice comparative graphics brought to our attention by member Johnny5.

2.5 miles.

Go to the first link in this thread and open it (eskimo something). Scroll down to the Maximum Range Calculator and open it. Enter your known data and calculate. I did your calculation using 1400 feet per second velocity, a Ballistic Coefficient of .15 and a bullet weight of 40 grains and a G1 drag function to come up with 2.5 miles (one mile is 1760 yards so you devide the answer you are given in yards by 1760 for the answer in miles)

Probably one of the nest I've ever seen is here:

It had a read only section that will even give you the ideal barrel twist for a given load. You can compare several different rounds or variables.

I don't currently have the funds to a pda, but do have a ti-86 graphing calculator. does anyone know of a ballistics program that I could change into z80 (?) language so the calculator can recognize it. I don't have any programming software, but do know how to write programs in notepad and transfer them to my calculator. Any help on this would be appreciated.

Thanks for starting this post. Ihave always used the JBM calculater and have had problems at times accessing his site. It is real nice to have a downloadable one that can be placed on my computer. Like others mentioned, once I get my loads perfected I am going to make cheat sheets for my rifles.
Thanks Again-
John
