Re: Wind Calculations Brain Teaser
Here is how it works: Gyroscopic Stabilization and Aerodynamic forces. You fire one round with at 3000fps and one at 1400fps, from let's say arbitrarily from a 1:12" Twist rate barrel. The bullets are rotating at different speeds (3000 rotations per second and 1400 rotations per second) and producing different induced forces (thing back to physics- that right hand rule, aerodynamics-wind cocking, spin induced yaw, etc). Time of flight may be the same for your scaled ranges but the forces are not. To get back to the induced forces... if I drop a bullet in the wind from a fourth story window it will impact on level ground the same time as if I fired a one level, but the wind drift will not be the same, it will be substantially less than the fired bullet (doesn't that stink). In those two or so seconds, the bullet is not being pushed by wind alone. Resisting forces increase (and not proportionally, but exponentially) with velocity. That is why your wind drift is different. Fluid dynamics are not directly scalable with size or velocity, so you've got a losing experiment for your purposes by retarding your load. Just like sex, nothing is like the real thing.
If you are interested in getting a reduced load for whatever purpose, go to a high volume powder like Trail Boss. With a lot of extra space left a case you risk detention vice the desire deflagration. Detenation is very bad and may cause catestrophic destruction of your rifle.
