Using my Dillon 550b with Dillon dies I am having a problem with the bullet being seated to deep on about 1 out of every 5 rounds (200gr 45acp). The other 4 out of 5 are fine. What could be causing the flucuation, am I flaring too much or not enough and the bullets scraping the neck of the case and getting shaved off, or something else entirely. It seems odd that some of the rounds are OK while others are not.
Any ideas?
