Since the round will move slower in colder denser air, what would the best bullet weight to choose for Arctic conditions?

55 grain, so you get the most velocity possible?

62 or heavier, because you want more bullet mass since you won't have the usual high 5.56 velocity obtained when shooting in temperate/tropical conditions?

I guess it depends on whether you are hunting zombies or polar bears. With zombies, I'd go with the higher velocity 55-grain rounds to better explode their heads.

If you're going after polar bears, well, I think you'd be fucked either way because .223 is just going to annoy one of those monsters.

Please don't feed the bears...

Just guessing here....I assume you were talking about 55gr or 62gr lead core bullets? In my low opinion, probably not all that much difference.

If you are looking to either 55gr M193 vs 62gr M855 ammo, given all the clothes folks wear up in the arctic, maybe you are better off with steel tip M855 ammo. So go buy some rejected/surplused XM855 ammo from Federal.
