Has anyone run powders in QL?

I got a rainier ultra match barrel today, dies and 6.5grendel brass will be here this weekend. I have N133 and was thinking it might work for the 55vmax. I see it listed with the 65vmax in the 6arc gas gun (hornady manual). Would the 6arc starting loads be safe or would the smaller diameter increase the pressure too much?

Eventually I’ll probably use the 62eld vt but I’m guessing it’ll be a wait.

Thanks in advance
