I highly suggest you get yourself a decent ballistics program. Info from those sites are pretty well worthless.
What makes you think your balistic program is any better than theirs.Thats all they use, some balistic program, which is still not 100%accurate. Only a speed trap will tell you that. But they are close enought for comparos.
I dont know what happend to that link i posted it was a comparo.
