I said I wouldn't comment, but what the heck, even John Wayne changes his mind once in a while.

I'm thinking one of the .20's, probably, the .204 Ruger for simplicity, is a good caliber - better than a 22-250, and a 6 mm is over-kill. Hunting will mostly be between 4-8,000 feet, probably works well

As Greg said, 1"circle @ 250 yds = .4 moa. A rifle capable of shooting .4 moa off a bench is not beyond reason, but @ 250 yards, better calibers are available and a Ballistic Coefficient of 0.275 (40 grain VMAX) would not be my first choice.

The rifle itself though... 10 pounds bare, I'm greatly deterred - roughly 13 pounds all up, plus everything else for a 5-10 mile walking hunt is more weight than I want for this
And then there's the field positions after a 5-10 mile hike @ elevations to 8000 ft. to contend with.
I can't speak for anyone else, but I live probably 30' above sea level and at age 64 & 65 made two trips to Colorado elk hunting (admittedly a bit higher than 8000' and at that time I had only 60% of my lung capacity) but I guarantee I couldn't have walked 50 yards and held 4 moa, let alone .4 prior to an 8 hour nap, and I had been running 40 flights of stairs 5 days/week for a couple of months prior.
Guess my advice, for what it's worth, is get the best rifle you can lay your hands on (which preferably shoots a bullet w/better BC than .275) practice, practice, practice, and in your spare time you could do a few aerobic exercises...hey, it can't hurt.
Above all, enjoy your hunt.
