I've done both, got rid of the 6arc as the 6x6.8 just does everything better imo. Strictly a coyote, deer, goat rig
I just run a 90g bullet.
No issues running it to 800 yards.
I did up a 6arc, bolt gun for a pal, runs 105g hornadys to 1000.
I recently picked up some 6 SPC dies from CH4D ... they had them in stock. Interested in knowing why you prefer the 6 SPC to the ARC?

I wanted to run a 90g bullet at 3000 fps at a minimum in my bolt gun build and a 55g bullet at 3500fps, 22" bbl.
6arc didn't do that when I built the 6x6.8, (6spc).
Simply necking 6.8 to 6mm, like the 6.5grendel to 6mm.
My 90g load cronies at 3068 fps, 55g load at 3570.
The 6mm arcs in the ar15 frame I assembled could not meet those requirements.
Nothing wrong with the 6arc, just didn't fit my needs.
Still using IMR 8208XBR with the 90 TGK's?
