The .244 Rem (6mm Remington) is basically the same as the .243 Win except for slightly larger case capacity.
It's still available, but never took off in the way the .243 Win did.
Probably similar to the Betamax vs VHS argument, Beta meant to be technically superior, but the marketing won....
the 6mm Rem is larger in all case dimension, bit more case slope (better feeding?) same barrel spec but slightly larger-than-groove bullet so it will swage down rather than the groove sized 243 that simply engraves rifling; greater inherent accuracy as well as velocity in the 244 ?? who knows, doesnt matter, 244 is dead.
But why the 'powerful' chamberings? like asking why the industry keeps developing more and more and more powerful cars.... because the consumer want them.... ideally the increased efficiency in engine design mean that smaller and smaller engines could be marketed to deliver similar power and torque at vastly reduced fuel consumption, but WHO want a smaller engine?? Commodores at one stage had a 4cyl engine!!! developing probably all of what 25 horsepower

yeah that went well, we know have 6L v8 developing ridiculous HP that, just like the ultramagnum rifle chambering; we dont NEED, but we WANT....
Back to the Nitro Express chamberings, Nitro represented the 'new' nitrocellulose propellant as opposed to the black powder, and the 'Express' was said to have been applied to such big boomers as they hit like an 'Express' Train..... sounds good to me!
