Ok boys. You all concede that twist rate has an obvious effect on bullet expansion (terminal performance). We know there is hardly any decrease in rpm's during a bullets flight time. Therefore you must concede that the bullet tests done by reducing the muzzle velocity, and therefore the rotational velocity, and then shooting into a test medium at close range DO NOT TRANSLATE into valid comparisons of the same bullet at full muzzle velocity shot into test mediums at long ranges.
