I would recommend starting from the 232 grain loading.
However, the closest I can find in jacketed bullet is 220grains (Hawk or Woodleigh).
Another option is to use the 3/4 rule, which is 3/4 bullet weight (174 grains) with same loading. It usually regulates the same as the full load.

Also Buffalo has a 208grs bullet in .327" from Prvi I think.
Might be OK.
