Thanks! Danke! Used a #17 o-ring, which Home Depot has (10 for $3). I did some tests and opted to use the metal LnL bushings for the resizing die, due to the high pressure of that station. I do lube my brass for reloading and then tumble the loaded rounds for 15-20 minutes, but I still prefer the metal ones for resizing. In a pinch you can probably get away with a printed one.
