I agree, W231 is a fine powder for what you are looking to do. I use W231 for loading 9mm, .38 Special, .45 Auto and .45 Colt ammo. I don't usually use it for middle pressure .357 Magnum or heavier .45 Colt ammo, that goes to HS-6 instead. (but you can use it for the .357 Magnum if you really want to)
