I don't normally engage in thread necromancy, I'll point out that barrel length has a role to play here.

a 16.25" barrel won't give you the same velocity as a 26" barrel, so having a tighter twist is not a bad thing here to ensure good stabilization.

I'd also like to point out that flat based bullets are generally more accurate at short ranges than boat tail based bullets. So I would expect to see a 180gr flat based bullet shoot very well at 100 yards from any 1:10 twist barrel of reasonable length.

You can't tell by twist rate what bullet a barrel will shoot best, but the answers given are all good places to start.
