Bullseye? Any powder measure I have ever tried--provided the pistol rotor or small pistol bar is used.
Really, no powder measure will be on the market long if it can't meter Bullseye well.
My favorite measures are Lee and Hornady, but, as I said, ANY will work, if set up for pistol charges.
What you are trying to determine is the "best" powder measure out of all the powder measures when they ALL throw to +/- 0.1gn.
If that is not good enough, then the BEST powder measure is the RCBS ChargeMaster or similar.
