Don't use that powder With that bullet, it's waaaay too fast. Well suited to a 155gr. With a 208, you will need a much slower powder. Not sure what as I don't shoot something so heavy - 12-twist barrel.

Yes, it's far too fast burning for the 208 - I assume we're talking .308 Win. It's a good choice in the cartridge with 155s, but I'd hesitate to try it with 185s never mind anything over 200gn.
For the 208, use Viht N550 or Alliant Re17 / Commonside Elcho 17, preferably in small primer Lapua 'Palma' brass with magnum or BR primers.
12-inch twist is also too slow for this bullet. It may just stabilise at short ranges. Long-Range performance will be inconsistent with poor elevations at best, dire at worst.
