Hornady's load data for both AR style and bolt gun are online at hornady.com, and the latest 2022 hodgdon manual has 6Arc data in it.
6mmArc Saami specs are also available online, just as an fyi.
In the 6mm, Hornady's 103 bullet is an Eldx, for varmint style I would suggest the 95 SST (although billed as a cxp2 bullet), 87 Vmax, 75 Vmax, Berger 88 FB, Sie 80-85, then several Nosler's of 70 gr, 80 gr etc... even a few at 58-65 grs.
I shoot a few of these in my 6 Creed and 243, and am evaluating which one I would like to do in my 6Arc.
Cases based on the 308 (and 30 TC) are too long to fit into an AR15 frame, that's why they are done in an AR10 frame. Several 6mm cartridges are designed for the AR15 frame, in addition to the 6mm ARC. 6mm AR, 6x45, 6 PPC, 6 RAT, maybe a few others. One difficulty some cartridges have in either AR10 or -15 is the shoulder angle, an angle too slight makes for some feed problems, or so I've heard. I don't shoot any AR10's, I use bolt actions for that size of cartridge.
