Dillon dies problem

[coban]

I am having trouble with my 9mm crimp die shaving the brass. It's almost like the die is beveling the case mouth during the crimp. Crimpimg to .3755 like I have in the past without problems. I am having this problem with different brands of brass and have cleaned my die.
Wondering if anyone else has had this problem and how they resolved it.

How much bell are you using. I've noticed that the more I bell, the more shavings I see.

I generally try to use just enough to keep the bullet from falling on the up stroke going into the seating die. Maybe my bell has increased a little without me noticing. I will adjust this tonight and see if it helps.
Thanks for tip.

I cleaned the die again and checked the bell and loaded 100 rounds. At first I wasn't noticing any shavings but by 75 rounds they were back. I haven't taken the die apart again to look at it. Just a little frustrated now.
I am considering just buying a 550 and getting rid of the square deal but I would still like to figure this out.

Have you ever chamfered the cases, inside and out?
Do you notice the cases sticking in the powder funnel/expander die?

No I don't chamfer my cases.
I pulled the die out and it had a copper ring in it. I think the die might be a little corroded causing the build up. I think I probably need a new die unless I can get it honed.
I also noticed the locking bushing on the powder die allows the die to turn causing inconsistent bells on the case. Probably a good time to send it to Dillon for a upgrade as this is an older press.
