1:8 will generally be adequate to stabilize 80s. 1:7 provides a margin of safety though. I have had a few 8 twist barrels on my rifles and all shot 80 SMK / Nosler fine. I use nothing slower than 7 anymore just because I never want to worry about it and I never know what I may get a mind to try to do.
