Do fast twist 243's make the 6mm Creedmoor pointless?

Better yet someone could start reloading.

But with companies like Tikka now offering faster twist barrels, maybe we should expect to see offerings from major ammo makers.

Tikka did that for the European market. A lot of mandatory mono use and they subscribe to the muzzle energy fallacy for killing effectiveness. Some monos are marginal in a 10 twist. Bullets just keep getting longer.

...and AFAIK you can't over-rotate a mono.

Retired my 6 MM Remington truck gun with a 6 CM a while back. 6MM was on it's third barrel, had a 10 twist barrel. The 6 CM is the ballistic twin to the 6 MM, I went with Benchmark 4 groove 7.5-1 twist on the 6 CM. I've been shooting 105 and 108 bullets in CM, at about 200 rounds on the barrel. I will say the 6 CM has been the easy button loading for a short action. Picked up factory loaded 100 grain Sig and Sierra ammo to try in it, and loaded some 90 grain bullets to try also. It's not much, but I've always liked having the performance of the 6 Rem vs the 243.
