I keep seeing people mention that their powder measure "leaks"? Where does it leak? I had a problem somewhat with this for a while with my 223 cases with my Uniflow, but realized the shoulder of the AI case was contacting the drop tube before the neck was tight against the tube mouth and it caused powder to fall around the neck and down to the shoulder - until I lowered the case and had powder all over my loading table. I was able to concoct a different drop tube set up with a smaller drop tube I had laying around- probably from when I had a 17 Remington and it worked perfectly for the 223 AI cases.... RCBS is really good about selling separate pieces if the right pieces don't come in your kit with the powder measure..
