Windage Chart

[bruce moulds]

similar charts can be generated if you have a copy of rsi shooting lab.
the big problem is establishing a b.c. for the bullet.
the best way to do it is to chrono the load, then use the velocity and established trajectory tto get a b.c.
only thing is b.c changes quite a bit through the transsonic zone.
they are very helpful charts.
keep safe,
