I had a hunch that you did what you did as I thought of doing the same,with my barnes program,just didn't take the time to do so yet.

I was hopeing that you might have had a formula or program to punch in the bullets numbers and get the Standing Still BC.

The barnes program has a BC finder that I will use later to see what it comes up with.However it bases it findings on the Caliber,Bullets Weight,Bullet Shape ie Spitzer ,Spitzer Boat Tail. Might get one reasonablely close but seeing as it doesn't take in the bullets lenght I question the results it gives.


I agree with your "caveat" and is one reason I have thought about getting one of the chorny garphs that est. bullet BC,by velocity,bullets time of flight. That however is going a little to far on the Ballistic Tech for me and my usees at present,just one of items that would be nice to play around with.

Actually, I do have a program that will do that, I just didn't happen to use it. It's called "Point Blank". It is an excellent ballistics program, will draw the bullet path, overlay up to 10 different paths on the same chart, do all sorts of wonderful stuff. :)I don't think a version is on-line that can be used without downloading and installing it on your computer. If you're interested in it, it can be downloaded at:

It is a free program and is better than a lot of the programs that cost $. Along with WinGyro (a stability program), it is the program I most often use.

will check those out.

Barnes 2.0 program
gave me a BC- 0.528 (Slender Spitzer BT) and a BC-0.462 (Flat Base Spitzer).

BTW - Glad we got on this subject as I found a glitch. Looks like it won't run after a recent windows vista reconfigation(SP) upgrade. In case anybody has both it won't run from the clicking on the icon,did get it to run from the disk.
