Have you tried the JBM website. It is easy to use, gives you everything that you could want and best of all it is free....

Re: Plotting a Graph from Known Drop Points?

Guess what, when I posted those drops, I looked at the wrong entry from my notes, as it turns out, I am 6" low at 400 Yds. all the other drops I listed are correct, but the 450 Yd drop of 14" is actually at 458yds. These look pretty close to the above chart. I'm using a laser range finder which I assume is fairly accurate, but I have not checket it, and I am using a base mounted level to keep things straight. Thanks for all the info, I'm going back now and running the programs again to see what I come up with.

Yep,the 400 / 450 was the biggest problem. Please report the results when you go shooting, this is always interesting.

Again,all this must be confirmed in real life. Means lots of shooting. [img]images/icons/grin.gif[/img] But I like playing with these,here you can find a couple:
