Lee Factory Crimp Die Binds?

The Lee Factory Crimp Die that I just started using binds or catches on something when a .45 ACP case is extracted.  Normal?

I have similar issues with my Redding crimping die although it didn't start until it was well used. It needs to be cleaned occasionally like a gun barrel.

You might be overcrimping and causing a bulge just below the mouth of the case. Try backing off the crimp a little.

Bees
The FCD I have and do not use much does not have the ability to crimp very tightly.  The area inside that crimps is smoothe only for doing a very light crimp.  Deeper crimps get roughed up beyond the smooth area.
Without entering deep crimp vs light debate, I use the Dillon crimp dies on lead bullets solely for the take apart and clean feature.  On Jacket bullets I use an old RCBS seater crimper w/o the seater, or a Redding.

Sounds like it might be cocking inside. Make sure the complete die is adjusted correctly.

Lee FCD is actually a simple device.  It is just an adjustable taper crimp that has a carbide ring around the bottom of the die that prevents the case from Squatting rather than taking on the proper crimp.  Results in a more consistent crimp.
First
Read the instructions that came with the die.
Crimp only to .469~.470 as measured at the case mouth.
Seat the bullet deep about 1/32" of SWC shoulder sticking out.  Seat from the shoulder rather than the nose with a special seater like Steve Bathje makes. 
I use a LFC with the crimp part removed to "bulge buster" the cases first.  Basically push them all way through then out the top.  Not only sizes deep on the case but removes any extractor burrs that may be on the rim.
Reload as normal seat in one die and LFC as final stage.

Reading online- A lead bullet may be sized smaller in diameter by a FCD? I dont own one, but it may be possible with thick walled brass and .452" lead bullets??

I took a closer look at the FCD and the Dillon crimp die for comparison.  Apparently, Lee makes at least 2 types of crimp dies depending on the caliber.  The one for .45 ACP functions the same as a Dillon with respect to the crimp.  The only difference that I can see is the clever and limited use of expensive carbide in the Lee as opposed to the Dillon.  The Lee has a small carbide ring that slips inside of the steel outer housing that produces the crimp and an aluminum cap on top for adjusting the amount of crimp.  The bind or hitch that I first mentioned and was concerned about is caused by the crimp ring holding onto the brass case and then releasing when it bottoms out on a stop inside of the outer housing.  It's not a problem after all, just a function of its design.  The Dillon has a similar release but it's closer to the initial down stroke and therefore not as noticeable.  Despite the irritating hitch in the FCD it does have the advantage of also sizing the case both on the upstroke and downstroke after the bullet is inserted.

Correction:  The crimp ring on the FCD may not be carbide after all, at least it doesn't look like it.  Maybe not important for performance or durability but the Dillon crimp insert is definitely carbide.  The sizing ring on the FCD is however carbide.

The lee FCD is useless if your loading process is set up correctly. imo anyway, as far as sticking brass, when you tumble the brass add a cap ful of liquid car wax to your media, and things will run much smoother, or buy the expensive tumble lube which is the same thing just twice as high for half as much.

I don't understand, why is the FCD useless?

As for the brass sticking, as I attempted to explain earlier it is simply a function of the case forced or wedged into a steel or carbide cone.  It would stick to some degree regardless of whether its lubed or not.  The release is only more noticeable on the FCD because of its design as I see it.

It's not useless, just not necessary in David's reloading.

I use it in my 9mm/.38 spec and .45 acp loading to guarantee 100% chambering. In PPC there are no second chances....

The lee fcd debate this has been hashed out on forums for years. The FCD is designed to fix a problem if your dies are good and correctly adjusted and you use good componets and Have good loading practices then you  should have no problem to fix. If this type of die was needed by all reloaders then every company would sell one. Not just lee. When ive loaded my rounds i check them with a check gauge and hen i have 100% confidance i will not have a ammo related issue. Google the lee fcd and read all the other opinions about how many feel it degrades accuracy, in some shooting sports thats not a big deal but in bullseye it could be. Do Some resarch then form your own decisions on whether this is something you need. I did years ago, dont need or desire to use it . Oh I do own one and have to used it to help come to my decision.

Like a condom, sometimes it's useful to have one handy....
