I'd be inclined toward the 9.3x 74R cartridge. In many European countries it is considered "the" wild Boar cartridge. It has better stopping power than the cartridges you were considering. At the same time it is not overly powerful for Deer. Since you'll be reloading, you can download it for small deer or keep it as is for Northern species. It also has better trajectory characteristics than many of the older rimmed cartridges.
