Is anyone out there reloading the .223/5.56 on a Lee Pro 1000? If so how are you checking the powder level in the case? I was setting up a Pro 1000 to crank out some AR-15 rounds when I asked myself the same question. And did not have a good answer. On the Pro 1000 the case is located in such a position on the press that you really have to go out of your way to look into the case after the powder dump. I may have to change my strategy and move to the LoadMaster! However I do love the simplicity of the Pro 1000.
