You might look at a gunshow for a powder measure. I have an old RCBS Combo that has the pistol cylinder with it. That's all I ever use and it throws almost all powders, stick, flat rounds, ball, really fabulous and accurate. The Lee dippers are a neat thing but don't rely on the chart in the box to be accurate. It can vary by as much as 2 grs depending on the powder. Make sure to weigh each charge until you get the hang of dipping powder. I use a custard bowl to put my powder in and dip out of it when using the dipper set. But the main point here is that you cannot rely on the chart with the set to be even close to accurate. You'll also find that different people will dip powder differently and get a different weight and do it time after time. So there is a learning curve with the dippers.
The 64 gr pills work great in most 223's. I use mostly the 62s. Varget gets me the most accuracy with that bullet. If shooting the 55gr pills, might consider AA2230. A max load of 25.0 grs works out of every 223 I've shot it in....and that's a bunch of 223's. It also throws out of a measure or dipper like water. You might wanna look to ball powders for your dipper loading. You find it will throw more consistently than a powder of a different shape.
