Re: 105gr berger VLD
Someone gave me this equation a while back. It is called the Greenhill Formula. Out of curiosity, I have done the math on a few of my rifles with the bullets that shoot well and it does work as long as one allows for some wiggle room.
- C = 150 (use 180 for muzzle velocities higher than 2,800 f/s)
- D = bullet's diameter in inches
- L = bullet's length in inches
- SG = bullet's specific gravity (10.9 for lead-core bullets, which cancels out the second half of the equation)
