I have w231 powder and would like to load for 357 brass. Have not bought bullets yet but have been looking at 146g JHP and 125 JSP. Is w231 a good powder for lighter 357 rounds?
 
Its a cheap way to make 357 target loads. As mentioned above, it has its limits, but for punching paper its an economical powder to use.

Here's some cut and paste from Chuck Hawkes site:

The Handgun Reloading section of the Speer Reloading Manual Number 13 shows that 7.6 grains of W231 powder will drive their 125 grain bullets to a MV of 1129 fps, and 8.3 grains of W231 will drive the same bullets to a MV of 1168 fps.

The 140 grain bullet can be driven to a MV of 1005 fps by 8.8 grains of HS6 powder, or 978 fps by 6.3 grains of W231 powder. I have found these to be useful practice and small game loads.

On the other hand, 13.1 grains of 2400 powder will drive the 140 grain bullet to a MV of 1219 fps, and a maximum load of 15.1 grains of 2400 will drive the same bullet to a MV of 1298 fps. These are good full power loads.

For heavy loads the Speer Reloading Manual Number 13 shows that 13.9 grains of H110 will drive their 158 grain bullets to a MV of 1151 fps, and 15.5 grains of H110 will drive those bullets to a MV of 1217 fps. These Speer velocities were measured in a 6" S&W revolver barrel using Speer cases and CCI primers.
