[Unclenick]

Bullseye's smaller grains meter better. Flake powders never meter great, but smaller is better in this regard because it is harder for small flakes to bridge a given span.

Neither powder is pristinely clean burning. Unique's formula was changed a number of years back to burn cleaner than the original, but I haven't used the newer stuff, so I can't say how much cleaner. For the light target loads I was using at the time, the original left a lot of unburned flakes behind, so I never took to it.

The main reason I haven't tried the newer version is that I discovered Hodgdon Universal Clays, which is cleaner burning and better metering than either Bullseye or Unique and which handles the functions of both closely enough for my current purposes. Most pistol loads of Universal seem to lie inbetween Bullseye and Unique charge weights, leaning toward the latter in my experiments.
