seating die shearing brass

my 44 special/magnum seating die "shears" my cases a little when I seat a bullet with a cannelure and crimp the bullet.
Nothing dramatic, but on just about every case there are brass "strings" or "threads" on the case mouth and on the bullet when I take it out of the die.
I've tried adjusting the die height and seating plug depth up and down and all around. I even tried holding my mouth different ways.
I use Lee brand dies.
am I doing something wrong?

I had this happening, or something similar on my 9mm die. I finally figured out what was happening. For some reason it would seem the roll crimp will get a build up of brass on it after a while. So I took the die completely apart. Soaked it in some solution and then clean off with alcohol. Works like it did when I first started.
what solution did you use to clean it?

I just use a q-tip soaked in some hoppes and clean the inside of the die with it

I think I soaked it in CLP, just because that is what I had on hand at the time. I am sure you could use mineral spirits or anything similar. I also cleaned the inside by scrubbing also, probably with a soft cleaning brush or something like that.

One thing that can help "cause" your problem is over belling the cases...try to bell the case as little as possible and still have the bullet be able to rest at the case mouth before seating...my 2 cents ..reloader44mag

I've backed out the expander die already. Maybe I'll try some more.

It may not be the problem, are you loading jacketed or lead

jacketed.
If you are not using a FCD, you may be having similar problems with the seating die. Take it apart and look at it under magnification. Look for a threaded like surface instead of a smooth surface where the die makes contact with the outer surface of the case mouth.
As you may or may not remember, I had issues with my Lee dies in 9mm, .40, and .44 Mag. The FCD would shave off bits of the case mouth and deposit the crud on the mouth. The problem was with the lousy job they did when cutting the mouth of the FCD sleeve.

FCD?
Sorry, Factory Crimp Die.[:I]
got it.
What Reloader 44 said, belling too much.
+2 I also expand the shell just enough to get the bullet in w/o problems.
