That is one very nice thing about Dillon dies, you pull one hair pin and you can take out the seater plug in the bullet seater die to clean it, and then put it back in without changing the adjustment

To start I would recommend cleaning the bullet seater die at the beginning of each loading session, the amount of gunk you find will teach you if that interval is too seldom or too often

My 1911 that I had built has a Clark barrel in it, against the advice of my pistolsmith I had him leave it as tight as it came from the factory in an attempt to get better accuracy, it was very very picky about brass brands and bullet dia. Once I let him open it up to where his years of experience taught him it belongs the gun is not picky at all.
