A friend of mine has this surplus powders (WC735).I can't find any data for it. This is a ball powder manufactured out of a plant in Florida. Where can I find data for that powder.I would like to load for .223

Thanks

  It seams to be about 10% faster than H335. That might put it about where 4895 or 2015 is. Look up the robertbank post on castboolits.gunloads.com.

  You probably won't find published data for a surplus, non-canister powder. Non-canister powders are sold to ammunition companies in bulk (up to a million pounds) from a single manufacturing lot. They do not conform to a standardized specification for burn rate, and so the ammo company has to develop load data for that lot of powder. When that lot is gone, there will never be another with exactly that same burn rate.
  
  The upshot is that you are pretty much in the dark with powders like that. You have to be, in effect, your own ballistics lab.
  
  One way to begin is to load a few samples using the Start load of what you believe is a faster powder. Compare the resulting velocity with the numbers for the known powder and adjust accordingly. (Yes, that first trigger pull will be scary!)
  
  Clearly, using surplus powders is not something for the novice or even intermediate reloader.
