bullet seating die issue
I have had an issue with the last two lee 9mm bullet seating dies I have had. after using them for a short time a ridge form on the inside of the die and that ridge begins to shave the edge of the shell casing.Can someone tell me why this is happening how to solve the problem and if this shaving will weaken the case? Thanks. Carl.

Re: bullet seating die issue
Are you possibly seeing the crimp part on the inside of the seating die. Try backing the seating die out a turn and see if the issue is still there. Come back and let us know what you find out.

Re: bullet seating die issue
Are you able to post a pic of the problem? Otherwise I'm stabbing in the dark at answers. It could be the crimp section like the previous poster said, it could be lead shaving from the bullet during seating is building up, or it could be something else.

Re: bullet seating die issue
I have removed the seating part of the die leaving just the die body itself and the die still shaves a flat spot on the case.I will try to post some photos if I can figure out how. But there is a ridge around the inside of the barrel of the die body. I don't use lead bullets if that helps . Thanks for the information.

Re: bullet seating die issue
I get that sometimes, but it is because I don't have the cartridge set properly in the shell holder. Check the shell holder for dirt or a small obstruction in the groove.
If all else fails--look for the obvious

Re: bullet seating die issue
I'm always quick to defend Lee but it could be a bad die. Don't give up yet though. Make double sure everything is clean. Let the solvent set in it for a while and see if any buildup breaks down to be scrubbed free.

Re: bullet seating die issue
flyboy, I see in your profile that your choice is the turret. Have you checked the index set up? I would say that the press is slightly out of alignment. I've had this happen. Every bullet seating die is going to have the ring you mention as it also must be capable of providing the crimp.

Re: bullet seating die issue
Thanks for all the great info I will work on cleaning things up.Do you thing it would help/hurt to run a brass bore brush thru the die? Also I have removed the indexing rod from the turret press and I rotate the disk by hand could this be part of the problem? Thanks.

Re: bullet seating die issue
I still think it is not a die problem but a "index" problem. Have you checked to see if the turret head is properly indexed (aligned)?flyboy wrote:Thanks for all the great info I will work on cleaning things up.Do you thing it would help/hurt to run a brass bore brush thru the die?

Re: bullet seating die issue
Could be the hole tapped crocked or out of alignment that the seating die is screwed into. That would through the mouth off the die out of alignment. Try shifting the dies 90 degrees in the turret. If the problem moves to another function it will show you the problem is in the turret hole spacing. I had a couple Loadmaster turrets that way.
