I have bought quite a few used dies over the years. Hadn't noticed a pattern of dies being screwed down too tight, but, my standard procedure when I get used dies home is to clean and lubricate thoroughly.
I restrict used die purchases these days to green boxes - had some bad experience with used dies from companies other than Redding or RCBS.
I'll tell you one big problem with used dies.
Down the road, you're going to see a rifle or pistol at a gun show or gun shop and say to yourself "Hey, I have dies for that." . . . . . . can be hard on the wallet!
