I agree with you Spaniel. If I'm working with a bullet that I don't have a BC for refrence I will sight in and then shoot at another distance and use the ballistics calculator to find the approximate BC as you did. I had to do that with the No Excuse 460's when I first started testing them. As you said, BC is somewhat fluid and a change of .01 or .02 makes little difference in calculated results within normal hunting ranges, many other factors will affect the bullet more thana small mistake in the BC of the bullet. As stated actual range results are the final word on the trajectory of a load, theprogram is just helping you predict and visualize the expected trajectory.

Chap,

I never thought about the ease of use of the Point Blank program as it was easy enough to use as it was. I do believe there are some instructions in the help screen if they are needed. It also has a firearm database to document all your guns if you want to use it. There are also some lists of bullets and there specs as well as some other things that I've never looked at included.
