Why not I run 85 grain 6.5mm bullets in a 7.5 twist grendel barrel just fine.
So I dont see why your light weight varmint 6mm bullets won't run from a 7.5 twist 6 arc pipe.
All it's going to do is make it have more spin. Not like your going to get enough velocity to make it separate the jacket from the core.
Folks been shooting the same thing for years as a 6mm grendel aka 6mmar and I know several guys shoot light weight stuff out of them.
