Concise and informative, thank you. Hearing that the correlations between wind deflection and velocity retention are linear is very helpful. I was surprised to hear that projectile weight has no bearing on BC calculations.
Mr Practical Tactical in one very short vid you have explained many hours of reading from books ( do u remember them ?) the concept of reloading for accuracy . Thanks very much . Cheers from New Zealand.
A real simple demonstration of BC is to take a sheet of A4 paper and try and throw it across a room . Se how accurately you can throw it and how consistently it travels in the air . Now take that sheet and crunch it up into a tight ball and throw that across the room . instantly you will see the difference . Both Projectiles are the same weight and the same material but the crunched up ball has the better aerodynamic shape and therefor the higher BC .
The number on the box is NOT marketing; the number correlates to the bullet profile under a controlled environment. When you're evaluating performance in real world settings, those values will obviously shift, but it's a reference point because you can account for different environmental conditions.
