I will second this. I have been loading some 303 recently and checking the loaded rounds on a concentricity gauge is a real eye opener. Would go from perfectly concentric sized cases to wobbly as hell bullets after seating. Definitely caused by the lee seating die.

I like lee collet dies a lot and use them for almost everything I load for. Advice above to keep the loads light enough that the cases dont need shoulder bumping and just neck sizing them with a collet die is good advice for easy brass prep, long case life and accurate loads.
