If you like to monkey with numbers, here's a few from a spreadsheet of about 125 loads (prospective, I don't own this much schit) that I've looked at over the years. Some like crossword puzzles, I like statistics.

Anyhoo....

Looking at BC and essentially MAX loads, you end up with the following median ranges of drift per "class" of BC. 500 yards, 10 MPH

.300 - .399 = 23"
.400 - .499 = 19"
.500 - .599 = 17"
.600 - .659 = 14"

I topped out at .659, but its as meaningful or meaningless as your ability to read wind. So 4 rifles with each class and we know the exact speed and direction, everyone hits. The difference though, would be the loss or gain in drift with uncertainty of speed and direction.

Summary: find a bullet suitable for the target you intend to engage and practice like hell.


Oops, dropped my pocket protector.....
