I don't recall having Lee make them.  We should consider a "bulk" custom order for cats like the Mongoose, Ocelot, Viper, etc.

I still have the dummy rounds Wikster put together to get it done, but just never got it done because the minimum is 25 for the order and didn't think the demand was there.

Make a deal, and if at least several more folks chime in here that they want an FCD for the Mongoose I will order them.

Does Lee make a FCD for a 6mm TCU? Or maybe 6X45. Bet one or the other would work.

But probably not. Assuming again. Lol

Lee makes a 6x45 factory crimp die. Hmmm, will it work on the goose?

6x45 is longer than Mongoose; so FCD would need to be modified.

Why crimp at all?

A lot of people don't believe in crimping, while a lot of people believe in crimping. 

It's not a debate to me, I want to crimp. It's that simple, so bring on the Factory Crimp Die.


Edited one day later to add, because lapriester's question made me do some reading: 
Just read BIGGDAWG's opinion about crimping here https://www.7mmvalkyrie.com/blog 
He has a good write-up about why he doesn't crimp. 
Soooo, my opinion might change from crimp everything, to only crimp plinking ammo, while not crimping target &/or hunting rounds. 

The one part of his write up I read which makes me more open to not crimping was he included a simple test to determine proper neck tension, along with steps to correct poor neck tension. 
'Testing neck tension is pretty easy.  Put the point of the bullet against a soft pine board section, and lean on it with your body weight.  If it doesn't move, you've got great neck tension.  Stop there and leave well enough alone.  If it moves, start measuring expander button diameters, inside neck diameters, bullet diameters, and so on.  You should have a minimum of .0015” less inside neck diameter than bullet diameter.  If the expander button is too fat, chuck your button spindle into a drill press, spin it up and take a strip of fine crocus cloth to the button and skinny it up to get to your desired diameter.  Use a light touch, and don't alter the shape of the button.  You just want to reduce the diameter a tiny bit where it meets the case neck.'  

I would still like to obtain a FCD for plinking ammo. My plinking ammo takes abuse, and a crimp on them gives me piece of mind.

How much material needs to be removed from the bottom of a 6x45 crimp die for it to work with Mongoose?

Based on SAAMI drawings, it appears the 6x45mm is 1.760" (MAX case), with a suggested trim-to length of 1.750~1.755".  Chamber wall is actually 1.7720"

The Mongoose is 1.700" MAX, with a trim-to length of 1.690~1.695".

Therefore, removing 0.060" from the bottom of the 6x45 FCD "should" work for the Mongoose.

Verify all data independently.

Thank you. I didn't know exactly how to determine the measurement, and now I do. 

I went ahead and purchased one of the cheap FCD 6x45 on sale at Midway since I have a friend with a milling machine and lathe who does small jobs like this for me for free. I'll make one to use for now until enough of us get together to create an order for official 6mm Mongoose FCD to be made. 

I loaded up 50 Prairie Dog bullets tonight, and then pressed a couple of them against wooden table. LTO didn't change, so it appears I have good neck tension, but I still want a FCD for plinking ammo.
