Winchester 296/Hogdon H110 is a powder which cannot and must not be used for light metallic cartridge loads! It is suitable only for full power magnum handgun loads and .30 Carbine loads. W296 is slow burning and needs a case full to ensure complete ignition.

Great powder for the heaviest .357 Magnum, .41 Magnum and .44 Magnum loads. See if you can trade someone for some HP 38/ W 231, Bulleye or Accurate #2- those are what you need and all are a bit cheaper than W296 so someone may trade.
