If I can add my 2 cents worth, my 7mm saum has a 26 inch McGowan in 8 twist. It shoots 168 vlds just fine.
I have seen lots of people order their 6.5 - 284 barrels in 8 twist.
I'm trying to bracket 270 caliber,.. If both larger and smaller calibers run well in 8 twist, then it's probably OK for you too. I don't know if you need an 8 twist, but a 180g .277 bullet is a long one and an 8 twist wouldn't hurt.
My 270 WSM has a 10 twist and it loves 150 g SGC bullets. I don't know if I can shoot 180s in my 270.
