Thread: Dented cases when sizing

Hey team,

Was doing my first batch of case sizing last night and when I finished I noticed all bar 2 of the 30 cases I did had a small dent on the shoulder of the case (wasn’t there before sizing). What could be the cause of this? Die not set correctly? Too much lube? And are these cases okay to shoot? All the lengths are fine and within tolerances.
Any additional information would be appreciated.

Cheers, 7RMBoy
