Universal. Smaller flakes and cleaner than Unique.
HP-38 and W-231 are NOT the same. Many of my load manuals prove it.

Your manuals are most likely old. The older data is indeed different. W231/HP-38 have been the same for years. They come from the same hopper in the same manufacturing plant. The only difference is the labeling. You pay a premium for the Winchester name. The powder manufacturer has addressed this issue already.
