Welcome abord: Burt
I have reloaded a lot in excess of 30 years. & have been quite passionate about the 6mm Arc for roughly 2 years. Though little interest in the 6mm ARC in a Gas gun personally. My initial expectation was Big Game may be a bit slow for this chambering. Keep in mind I have never loaded Big Game in any cartridge. Looked at the burn rate chart to ballpark verify, remember we are cautioned with making the burn rate comparison.
Though this is my educated guess& & we will use the burn rate chart to help a bit with our comparison.

Benchmark with lighter bullets is on the fast side for this cartridge at 85 . CFE223 & Leverevolution are dense yet on the slow side for heavy bullets for this cartridge at 111 & 113 on the linked burn rate chart. Ramshot big game coming in at 115. Id feel fairly confident that the burn rate & the bulk of this propellant will likely not meet your goal for your AR with the 6mm ARC.
Not sure what bullets you are considering for fire forming though Id encourage you to consult reliable load data from the likes of Hornady & or Hodgdon & consider other propellants that fall in the load data for your bullet selection.
