So is it safe to conclude from all the above analysis and charts that there simply isn't any ballistic curve that fits with all the numbers Frazier used or received in his experiments?
( muzzle velocity 2165, 15 yards= 4 inches high, 25 yards=4.5 inches high, 100 yards= 4 inches high)
If that is true, which assumptions could be changed in order to get the curve that Frazier describes: i.e. muzzle velocity? We know that if the FBI was using WCC bullets (.264 caliber) they might not have had the specified muzzle velocity for the weapon. Also the gunpowder would have been 10-20 years old at that point... Since Frazier apparently used textbooks instead of real measurements to acquire some of his numbers (like caliber and land/groove measurements), isn't it possible that he just picked a muzzle velocity out of a book instead of testing it himself?
