How to establish a wind bracket?

[BCD]

Can anyone walk me through the process or refer me to some info regarding how you establish a wind bracket (in MILS) for a given load?

Thank You!

The starting point is the first number of the G1 BC. That’s the baseline full value wind that will drift that bullet .1 mils per hundred yards. For instance: G1 BC of .545 has a baseline wind bracket of 5mph.

This can change around +/- 1mph depending on conditions, but is very close in mid range.
