I don't anticipate having one any time soon, but a 130 @ 2300 should be a decent performer out to 200 yards with the right bullet. Notice I used the words should and decent rather than would and solid. Minimalist performance doesn't impress me, and there are suitable moose rifles out there chambered for full sized rifle cartridges. I don't get why you would want to spend more money so you can do it worse.
Once upon a time I envisioned a survival rifle based on a Contender fitted with a folding pistol grip stock and a mini scope chambered for the 6.5 TCU. The 6.8 is just more of the same, and would fill the niche equally well. The ammo is small and light which means you could carry lots of it, and the rifle should prove accurate enough to kill geese and small game, with enough power for caribou if you found yourself in dire straights. With longer range than a .22 rimfire, and better wind bucking than a .22 Hornet, in theory at least you could eat more regularly.
