Hey there I would suggest maybe a different recapping die if your still haven problems with the lee set. Like others say make sure the decapping pin is centered. I don't have much experience with lee dies but I can tell you rcbs and hornady custom grade dies you set it and forget it with them. No going back re tightening all the time. I have heard good things about lee dies but haven't used any just my experience with other brands. Also you can buy just a universal heavy duty de capping die. Hope you get it working good
