The 6mm creedmoor case was based on the 6.5 creedmoor case. Which was based on the 30 TC case. The 243 is based on the 308 case.

The advantage of the creedmoor cartridges over their 308 based counterparts is this. Having a shorter case allows you to seat the bullets further out of the case and still fit into a standard magazine. Eliminating some of the space that the long bullets protruding into the case of the 308 based counterparts. Increasing Available space for powder in one way.

The sharper shoulder and straighter contour of the case walls allows increased powder capacity in the shorter case. Also the 6mm creedmoor will have a tighter twist rate to stabilize those heavy for caliber bullets.
