Suggest no more than 6 rounds of ammunition. (It's heavy, and if you can't hit and kill an animal with 6 rounds, you may want to reconsider the shots you're taking.)
Not to quibble too much but things can go wrong. In 2016 I did a solo sheep hunt (Alaska) and took 12 rounds. I'm not sure why I took 12, usually I just take 10. Anyway - somehow my scope got bumped on the flight in; I usually check by boresighting once I'm on the ground. Once I was sure there were no sheep near the airstrip I sighted in at 200 yards and it took me 4 rounds to get to where I felt I needed to be (within a few inches). So I started hunting with 8 rounds.
Some days later I ran into a grizzly sow with 2 yearling cubs. After some antics by the cubs that had me on high alert, Mom rounded up her charges and they headed off in orderly fashion. No shots fired, but believe me I was counting rounds!
A couple of days later it took me two shots to harvest a ram. This left me with 6 rounds for the walk out, wondering if I was going to run into those bears again. Which I didn't, fortunately.
All that to say it's worth considering 1) whether you might need to burn a few rounds to correct a bumped scope; and 2) whether you want a few extra rounds to deal with bears. Ammo for my 7mm-08 is right around 1 oz. per round.
