.243 with the 115Dtac is a tough combo to beat in those matches. Plenty of energy to knock down steel and is like a lazer getting through the wind. Combine all that with light recoil (or no recoil with a brake) and its only downfall is a short barrel life.
You can correct that by going with longer neck. I have a friend who did just that with his .243. He pushed the neck shoulder junction back and still gets about the same velocity. I don't know what he calls his wildcat.
