I think I have finally figured out the perfect amount of case lube to use for my setup... I haven't gotten any cases stuck in more than 1000 resizings. Prior to that, I think I got a case stuck every hundred or so. Then I used too much lube and the lube built up on the inside of the die, causing dents on my case shoulders. Then not enough lube and I got several more stuck... I have about 600 more pieces of .223 brass to resize, then I'm done for a long time with .223 resizing.
