Cartridge comparison

.243 Winchester vs 6.5 Creedmoor

Typical factory loads side by side: speed, energy, BC, twist, range and what each one is built for.

The short answer

With typical loads, the .243 Winchester is about 260 ft/s faster at the muzzle (2,960 vs 2,700 ft/s).

The 6.5 Creedmoor carries about 19% more energy at the muzzle (2,315 vs 1,945 ft-lbs), which usually also means more recoil.

The 6.5 Creedmoor's typical bullet has the higher BC (0.623), so it holds speed better and drifts less in the wind at long range.
