Does anyone have a picture of a correctly crimped .223 cartridge?
I just made my first dummy round to check OAL, I have the case mouth centered in the cannelure, and i crimped. I was under the impression that it would just "roll" the cartridge edge over slightly, but what I got was about the top .03" of the casing is kinda pressed into the cannelure. I am using a Lee FCD. I would post a pic but i dont have one of those fancy digital camera thingys. Thanx for any help!! P.Smith |

That was a requested picture of those 3 particular loads.. After they were loaded, I put them back in the lee cutter mandrel, and polished them up with steel wool, then amonia free metal polish.. You just add a little to a patch, and hold the round while you spin the drill for around 5 seconds.. I dont do that to all of them, but I did for that picture...
If I remember correctly, there is a 69gr hpbt.. a 55 gr spbt.... and a 55gr fmj.. |

The Lee FCD doesn't roll crimp. Anyway, lots of good pics here from babob http://www.ar15.com/content/page.html?id=404 |

The FCD doesn't roll crimp, It uses a collet to *squeez* the brass onto the bullet. Depending on how tight of a crimp you do with the FCD it will leave a nice crease in the case mouth after fireing and resizing! (I even E-mailed Lee to verifty that was in fact "normal") I am new to reloading too, but so far I'm not all that impressed with the FCD, Mainly the crease it leaves in the case mouth. A Roll crimp seems more logical to me, but many people swear by the FCD.. I also don't know where the "Factory" comes from in FCD because I don't *think* factory (Commercial) ammo uses a collet type crimp, maybe i'm wrong!? If they do, the factory crimp's don't leave creases like the FCD does.. If you want to do a standard roll crimp, you can do that via your Lee Bullet Seating Die (Assuming you are using all Lee dies). -Masta |
