Not in my experience with loading lead cast rounds. I believe in the old thinking as to just how did so many millions of rounds were reloaded before Lee dreamed up this die. As far as having a tight chamber, the chamber MUST meet SAMMI soecs, I have a Ed Brown Match Barrel with a xzxzxz chamber. My problem with correctly adjusted dies? None!
With the above said, I am a fan of Lee Products and YMMV.
