Not really all that strange considering it was specifically designed for an AR15 platform. No one was hunting with ARs 70 years ago. So, what's your point? I've never denied that the 6ARC will kill deer sized critters.
The point is if it was less effective, or less efficient at doing so, than the .243, it wouldn’t have been developed or selected.
You gave the impression you wanted low recoil, lightweight, low budget gun with factory ammo available - with a wood stock. You mentioned some options.
There’s an easy button for this, but you continue to say that it’s not better than the .243 for your purposes. It is. Because it’s as effective, and more efficient. It doesn’t need 47 different factory ammo options because the ones available are designed and optimized and really efficient at killing.
This is all leaving aside that the difference in recoils is more significant than anyone who hasn’t shot a 6ARC a few hundred rounds, especially in the same shooting session as the .243(in my case 6creedmoor), can give credit to.
It is a demonstrable difference. And my 6cm weighs almost 12lbs, versus under 7 for the 6ARC.
Somebody said it in another post elsewhere - just get the minivan.
