I'm just now starting to reload for 5.56 x 45 and am curious what crimp everyone prefers. During my research I found that it seems you can either put a slight roll crimp or use a Lee factory crimp. I am leaning towards using the Lee crimp but I was wondering if the crimp messes up your brass for future reloads? I will be shooting these reloads in an AR 15. So can someone explain the Lee factory crimp device? Thanks
Lee FCD is the way to go. I've loaded and shot thousands of rounds of 223/5.56 and the Lee Factory Crimp Die gives me consistancy and reliability over other crimp methods. Lots of guys say they don't crimp, but if you don't, you will likely get a bullet pushed back into the case. At minimum a mess to clean up, and can get dangerous.
I've loaded thousands of rounds of .223 for competitions, using a light roll crimp. It does not "mess" with your brass.

I should have been more specific. What I meant was I was wondering if using the Lee crimper messed up the brass any with its specific crimp technique.
I have used a slight roll crimp on some of my pistol ammo. I usually don't crimp pistol ammo but have in the past put a slight roll
Crimp on some ,45 and 9mm used in semiautos. I too have never had a problem using a roll crimp and have never crushed any cases that way.
In your competition shooting are you shooting semiautos or other rifles?

FCD on all the 223 I reload. Have reloaded some cases 10+ times before some sort of failure, which is pretty good. Hard to beat that factory crimp die.
You want to be careful of roll crimps on semi auto cases, they headspace on the case mouth, should use a taper crimp on them. Jim
5.56 headspaces on the shoulder.
come to think of it, so does .308 and 50BMG
