It's doable. A drop tube would help with a bullet seated to the boat tail transition.
When I tried loading the 230 berger with H1000 in the 300 WSM, the charge I needed filled right to the base of the neck at 71.5 to 72.0 grains with a drop tube funnel. You could be talking a full 2 grains more powder for the 208. The Norma case will hold approximately 74.5 grains of H1000 filled to the top.
