I am running a Lyman .356 sizing die in my LAM II and am having a bit of an issue, the bullets are getting sized, but every single one is sizing either .357 or .358, is this a known issue or did I get a funky die? I zeroed my calipers, I checked them against known sized bullets, and all my 9mm are sizing incorrectly. Am I doing something wrong or is it time to contact Lyman?


ETA: Lyman .452 die sizes my bullets at exactly .452

Are the bullets being pushed into the die deep enough?       Some dies will need adjustment by Lyman. I have sent a few back. Lyman claims that different alloys will spring back after sizing, some more or less then other. But i feel anything over .001" is to much. Photo Albums Link
