I've found that the settings that Browning gives on their website may give the best performance with one or two bullets near the same specs, but most of the numbers are just a starting point. I would expect that 30/06 to not be unlike my 270 stainless stalker w/ BOSS. I can get sub 1 MOA with better BOSS settings. It does make a difference with all cartridges I've tried so far with varying degrees. With 130 grain winchester power point it was very significant for my gun.
