If dies are the problem, use a Redding Type S bushing die for 6.5 Grendel with a .268 or thereabouts bushing in it (a nitride bushing is good). It'll work fine for necking down 6.5G brass and working with it from then on.
For seating a 6mm PPC die works, like one from Forster.
Those are what I used (which I no longer need and will list in the classifieds when I get around to it) when I was loading 6mm AR.
edit: right or wrong, I assumed the topic had to do with 6mm AR. Oops.
