For a light-bullet load I would start with any of the common 139-145-grain bullets and 45 grains of H4350 or Ramshot Hunter, and work up until muzzle velocity gets around 2800. This usually shoots pretty well.
With 175's either H4831 or RL-22 usually works well. I'd start around 40 grains and work up toward 2400 fps.
Or you can just load a 154-160 grain bullet for everything, with H4350. The heavier bullets may shoot better in this rifle due to the long military throat that it no doubt has--though I once had an 1895 Mauaser that shot very well with 130 Speers, despite the long throat!
