I use the Lee automatic powder measure with adjustable charge bar and it works great with light loads. It generally throws +0 / -0.1 grain of what I have it set for so it's operating in a 0.1gr window. Most digital scales are +/- 0.1gr so it's within the reading error anyway.
To be honest though, the very light-charge nature of Titegroup caused me to move away from it. I was getting significantly larger extreme spreads for velocity than with any other powder I've tried because it uses so little. The same variation in charge weight compared to other pistol powders causes a much larger swing in velocity. It's the cheapest powder to use because you can use so little but personally I don't care if I'm getting 20% less rounds out of a pound if it means more consistent ammo. The difference in price of other more user-friendly powders is insignificant compared to all the other components. I've had excellent experiences with dense, hard-grained powders as they tend to flow better anyway. Powders like HS-6, Longshot, and CFE Pistol.
