Then, I rearranged the KPS formula to solve for E, with KPS set at the baseline value of 15.0 and (SD x A) = .0112 for the 100 grain .243 bullet. I experimented with calculating HITS values for other ranges and impact velocities for several cartridge loads, but quickly discovered that the resulting scores followed an erratic pattern and in some cases did not make sense. 243 will shoot a little bit flatter, but the 308 is the better all around round (imo). SST, MV 3125 f.p.s. is an outstanding caliber and for the gear head that I am the 243 WSSM is just as outstanding.

Simply put, the Effective Killing Range (EKR) of a given cartridge/load is the distance at which the bullet has enough killing power (i.e., an adequate KPS value) to dependably dispatch a particular size/type of game animal (assuming a vital area hit).
