And that is the best way to fix the problem. I had to send my 38/55 seater back to Lee to get it opened up. My 444 seater had to go back and they lost it, and I had to request a new flare plug. The original plug acted more like a neck expander and a .431 bullet would drop right in. Lee was never great, barely good, and now they're just plain old bad. I'm glad my 45/70 dies from them at least work well.By the way I fixed the problem, I bought a set of Hornady dies they work a treat.
