First of all if you hear a horrible crunching sound using any die then there is a big problem somewhere!
If you need a certain size ring for your die, I believe Lee will polish one for you so you won't have a problem.
I look at the die as an "on the press" size checker. If I feel resistance as the round goes in then I know there was a problem somewhere else in my reloading sequence. I would rather catch a problem early then have 100 rounds reloaded that I have to later pull to correct.
