Am a 100% reloading novice so please take it easy on me if this is a newbie question. I was running some cases through the FL sizing die and noticed that for some reason a "ring" appeared on the case. I fiddled with the die some but didn't seem to matter. Am I making some kind of rookie mistake/have something set up improperly that's an easy fix? Not sure if it matters but is a Lee FL sizing die in 300WSM.
