As a pal of mine used to say, "It won't do em any good!" That said, for moose and elk I would prefer a 140/7mm in the 7-08 and a 160 in the larger case 7mms, the heavier bullets may prove advantageous in the event of a quartering away shot if a classic broadside shot is not available.
The maximum range of any load is described by your ability to shoot at those longer ranges, in the conditions that exist at that moment. I would limit my range to the distance that I could place my shots within 4" of my intended point of impact at that moment. How far can you shoot, and keep your shots within 4" of your intended point of impact with that rifle and load? Does you scope's magnification allow you to see your target clearly at longer ranges. Does the POI change as you adjust the power setting of your scope? How are you at estimating range and do you use a laser range finder? If you use a laser range finder, have you tested it in bright sunshine over snow? Can you dope wind? Will you click for wind and range corrections or will you hold off. If you hold off, does your scope's reticle have usable hold off points?
You can get all sorts of reliable and unreliable, honest and dishonest field reports on a public forum. Its left to you to load some ammo and go out and shoot under a variety of conditions to see if your expectations are realistic. Once you've done that, you are in a much better position to assess your ability to use your rifle and load. Whether you use heavy bullets or light, large bores or small, the math is the same, if at the shot, your target doesn't respond the way you think it should, keep the butt in your shoulder, your sight on the target, run the action as fast and as hard as you can, and continue shooting until you achieve the results you're after. Once you begin butchering your game, you will know if that's a bullet you would choose to use again.
