IMO, the only stat worth looking at is ft./lbs. All the other "formulas" don't amount to a hill of beans. Ft./lbs can very loosely be used to compare one round to another, although there are problems with this as well. xxxxft./lbs out of a .22-250 vs the same xxxx ft./lbs from a .30-30 are two different animals. There are just too many variables to have any one formula work. Bullet construction, weight, nose type, diameter and intended use all contribute to foul up a formula.
