Tfox your obviously seeing what you want too see, that graph shows me that the difference in bullets is what makes the difference not KE
Heres another graph
Note the .223 has less KE than the 30-30 and the 12 gauge slug but has a bigger wound channel.
Velocity baby !
The .223 Remington has a KE value of 1102 fpe.
The 30-30 has a KE value of 1536 fpe
The Foster type rifled slug has a KE value of 2222 fpe.
