eg. If you check the data on the program above with 2 bullets.
87 grain V-Max = 1.037" long.
80 grain Berger Varmint = .925" long.
Add that data into the online software and play with the velocities and see where the bullets lose stability with a 1 in 10 twist barrel.
87grain V-Max starts to lose stability at 2720fps.
80grain Berger starts to lose stability at 1300fps.
I then look at the exbal data to see at what range the bullet reaches that velocity.
You will then see that the Berger bullets retains stability a lot further down range.
Do you understand what I am saying now ???
Or am I just totally wrong here ???
