A better starting point would be with 6mm PPC data instead of 6BR Norma. VV, Western Powders (Accurate/Ramshot) & Nosler have data for the 6PPC. VV data is with 68/70gr bullets & N120, N130 & N133 powders. Western data shows bullets from 55grs to 107grs using their powders. Nosler has data for only an 80gr bullet. The only VV powder they list is N130.
6mm PPC brass has a bit smaller case capacity than the 6mm ARC. It would be better to load up from the 6PPC than down from the 6BR Norma. I have some 6mm ARC reloads (103gr ELD-X & 27gr AA2520 in resized Lapua 6.5 Grendel brass) ready for shooting. I used the Hornady manual data as a starting point. I have N133 but didn't use it for any of my loads. The only data I've seen using N140 for 6mm ARC are in 6mmAR's loads & in the Hornady manual for gas guns (108gr ELD-M & 110gr A-Tips). Even though Hornady lists that data, I'm thinking N140 is too slow for the 6mm ARC. There's no data for N140 in Hornady's bolt gun data.
Edit: Found 6mm PPC data in Hornady's manual also.
