+1, it takes literally 2 seconds to pull the retaining pin and remove the die. I love my 550B.If you are having a problem with lube building up in your Seating die, it is probably causing a decrease in your OAL, a bad thing. Because of this problem, I like the Dillon Seating die in pistol calibers: it can be disassembled for cleaning withou losing your settings.
