I ran into a similar problem, and solved it completely by discontinuing use of my Lee carbide set, and buying a Hornady die set. The sizing insert on the Hornady sizing die is longer and I think does a better job of not sizing the case down too much at the case mouth end. I also use a little Wilson gauge, and make sure that the tip of the bullet is just poking out of the gauge when the round is inserted. When I used the Lee dies, I would also notice that loaded rounds would clatter when they were rolled on glass. The Hornady seating die is a pain in the neck to adjust but also completely resolved that issue. OP, I can tell from your photo that the bullet on the left is seated cock-eyed for the lack of a better term. Rolling it on a glass table top, when your wife isn’t watching , will tell the tale.
