Lee Auto Drum Upgrade kit
I want to thank Viejo(Walter) for bringing this to my attention... I had no idea that this even existed until I saw his video. This has been needed for a looong time. Once you got the powder measure installed and had to move it it was one giant PITA! That skinny knurled ring simply wasn't large enough for a grown persons fingers to unscrew the powder measure.
