This is the 130GR Norma with 29.7grLVR that I was shooting.

Well, if you are getting .97 and it isn't going over, your calculation is wrong. Just not sure how wrong. That equation is bizarre because they seem to be taking a value at 200 then using a constant to estimate a figure at 500 when all they need to do is figure it out at 500 M (550 yards).
I bet the calculator I used is more correct but I need to learn a lot more about how mass is used for this purpose. Too bad someone can't just come up with a simple thing like a Power Factor where you would use velocity at the target, sectional density, and bullet weight. I bet bullet construction has a lot to do with it too. And a bullet that retains its mass when it hits will exert more force than a bullet that disintegrates.
A lot of stuff to consider.
