I recently stumbled across one of these which roused my curiosity so I bought three of them. The price is quite reasonable and so far I like the results. After becoming interested in these I ran a search and found a couple of you guys use this. This is an easily overlooked item but the design is rather interesting as it has a bushing wiht four cuts in it that rides upward as the bullet is inserted. It does not alter the length but it can be adjusted from a light crimp to too much but for semi auto guns I think this would be a dandy idea.

I like 'em. They are especially useful after neck sizing with the Lee Collet Neck Sizer. The Lee Collet Neck Sizer does not size the inside of the neck much smaller. The mandrels are .001" to .002" smaller and that does not make for a lot of bullet grip. The Lee Factory Crimp Die helps hold the bullet.
In my tests that have slightly increased velocity and slightly decreased groups size.
The only detriment is that when you chamfer enough to remove the material at the mouth that is boogered up by the crimp, your case will get progressively less in length. After about 6 or 7 loads the crimps will no longer work as the case is too short.

There are valid reasons Lee "Factory" crimpers, rifle and handgun, are the most used, certainly by those familiar with them AND use them correctly. (Not everyone uses them properly)
I've never seen any reason to re-chamfer any cases crimped with any die.

I use these as well on all rifle loads with the neck sizer and on some pistol loads. I like them. I probably should expound more to make this post useful.......

I too use and like the Lee Factory Crimp Die. If you look at I believe it is FC loaded rounds the crimp on them looks just like the one you get with the LFCD. I have found them to be a must if you are gonna hunt with neck sized cases.

We measure it with a micrometer, mark it with a crayon, and cut it with a chainsaw.
