Could be. I tried it with the lowest BC Hornady lists for it but it didn't change it a whole lot though.
Klem,
I'm also curious what the real data is, just wanted to see if anyone had real experience to compare the computer numbers to. OR if anyone had any real life experience in the differences between 4DOF and the various BC versions. I'm stuck at 100 yards except for very special occasions so wanted to be prepared as much as possible.
