I read both taylors work and the book about taylor by capstick. All the formulas have their place and none are without exceptions. People dismiss ke and just dont understand what the formula is trying to describe nor how to use it. When used appropriately it gave give you a guide in certain elements of terminal performance and so can taylors but in the end i think both are nonsense used as a stand alone and unlike tko values gun writers use KE to describe that which it was meant to describe. It is simply describing the ability of an object in motion to do work. If there was a projectile out that could handle the velocity of 10000fps it would be very destructive even if it was 22 caliber. Its no secret what works in the hunting realm and newer and better bullets keep changing what we can use effectively. No formula tells it all
