Given a pure set of constants for Barrel twist, wind velocity and direction (symmetrically) does bullet drift the same (distance) for a right left wind and a left right wind?

The simple fact is that a bullet will ALWAYS BE DRAGGED OVER BY IT'S BASE, in other words, a bullet follows it's TAIL, not it's nose.......Is this "drag over" velocity relative? Or in other words is it the CG weight that wants to pass as velocity slows?
Ken
The bullet orients itself toward the center of pressure. So, if the wind is coming from the right, the bullet will point (slightly) to the right. That means it's base will "point" slightly to the left. The drag on the bullet, then, will be slightly right to left, so the bullet moves "left" as viewed from a downrange perspective. Movement from the wind has nothing to do with the Center of Gravity of the bullet, everything to do with drag.Is this "drag over" velocity relative? Or in other words is it the CG weight that wants to pass as velocity slows? Ken

Charles is right, BUT.... I get the sense of another question in your post.
You ask, "Is this "drag over" velocity relative?" and to this I must answer with, "I'm not sure what you're asking"....... The "drag over" is directly linked to the "RATE OF SLOWDOWN," the RATE of deceleration of the projectile. The faster a bullet is slowing down, the further it's dragged downwind. Initial velocity has negligible effect (within reasonable, usable shooting parameters) and CG has nothing to do with it, at least nothing directly.

I have heard talk of this from some. Is it possible to see this drift using a PPC at lets say 100 - 300yds?
Thanks

No.Please clarify: Would not any forces put on bullet from the wind (Top or Bottom) be equal? I would have thought that a bullet would orient itself around its mass or CG.
What I was talking about is that some ranges a left to right wind will push a bullet farther than the same velocity right to left wind. I don't know why but suspect that the layout of the terrain is the reason. But I have experienced this a number of times at various ranges, Fairfax Va. for one that comes to mind. Steve
