I think some research will show that 1F or 1.5 F Swiss is very close to the powder in granulation, charcoal, manufacturing techniques etc, used in the original cartridges. Greener specifically stated that fine grained powder should not be used in express rifles.
I would use Swiss 1-1.5 and 2 and try both Federal Magnum rifle primers and various standard primers to get best accuracy. The best accuracy is often from pistol primers but these can cause problems if the breech face is soft.

I had a 450 BPE double that I could never get to regulate properly with Goex and wonder if Swiss would have worked if I still had the rifle

This rifle had a 40" twist so look at this when looking for bullet weights.
