I think that guy is full of it. There is a problem with Unique-it clumps up due to the size and density of the granulkes, so must be weighed-it DOES NOT meter evenly!

For handguns, I do use Unique, Bullseye, WW 296, Hodgdon H110, Alliant 2400, Red Dot, Blue Dot, HS 6, HS 7, and IMR or Hodgdon 4227. HS 6 and HS 7 meter accurately and are suitable for both reduced and heavy loads. I still prefer 2400 in my full-power .357 loads. Plus it meterswell and is not near as sensititve to crip as are WW296 or H110.
