I have a 6.5X55 that really likes H4350 and almost every 120 - 140gr. fed to it. Lapua brass, Winchester primers, H4350, almost any/every 120-140. I have not shot anything lighter nor heavier.
139s and 140s shoot great.

HOWEVER ! I'm shooting an 8 twist. So that may not be much help to you.

BE STRONG IN THE LORD, AND IN HIS MIGHTY POWER. ~ Ephesians 6:10

Socialism is a philosophy of failure,
the creed of ignorance,
and the gospel of envy,
its inherent virtue is the equal sharing of misery.
--Winston Churchill
