.45 ACP Mouth Bell

I am having a real tough time setting up my .45 ACP dies and am looking for assistance.  After loading a few thousand rounds I switched to another caliber. 

Bye the way, this is the reason you should purchase equipment for complete setups.  I have since ordered more powder measures and stands.

OK so I reset up the machine, pushed out a few rounds, tested them and then started serious production.  When I went to the range I had problems.  The bullets or bullet jackets were over the case mouth and they would not headspace correctly. 

I have since tried to get it reset and either the bell is so extreme it weakens the cases or it isn't open enough.  I would like a different angle on the powder drop/case bell but that is not an option.

What have others done to get the belling process adjusted well?

Set the flaring to flare the case .010" larger than the mouth of a sized, unflared case.

Adjust the bell?  is your lock nut snug? are you taking off the dies every time you load.  Once you set it... its done.. check it always but it should not change.
