For 230grain bullets a good load of Win 231 would be about 5.5 grains. Winchester says 5.7 grains of Win231 with their 230fmj bullet is maximum and it shoots fine in my .45's but 231 is not the powder for highest velocities. You could start at 5.3 and work up to 5.7 and see what your gun or you prefer.
