Oh man we can go around and around on this one. There must be a type-o on the partition that you talk about cause this doesnt look the same. Take a look at the link at the bottom.

All Ive' been saying all along is the .243 is a duall purpose gun, it can do what the 25 does and also be a varnint gun. No doubt they are very similar performing guns, you cant deny that, the 25 does carry a little more energy though, but everything I find shows the .243 to be flatter shooting, with better accuracy.
Heres another comparo.
