How much crimp on 223 using Dillon press

[masterkwan]

I am almost done setting up my Dillon XL 650 press to reload 223. My question is how much crimp should 223 have? I am using Dillon dies.

I am a big concerned, but I followed the directions. I basically screwed down the die till it touches the shell plate so that it touches the bullet. I then turned the die 1 full turn and screwed everything down. I measured the neck of the case with bullet before and after the crimp and I get the same measurement. Is this right? Am I doing something wrong?

Anyone in Bakersfield that woudn't mind coming over? A free lunch would be offered.

Thanks.

I almost never crimp rifle ammo. Since .223 doesn't have a lot of recoil or use a tubular magazine, most consider it unnecessary. If you are belling the case mouth to make seating easier, you would probably want to "crimp" just enough to remove the bell. Other things to look at before you crank out alot of ammo are COL to make sure they fit in the magazine and "cartridge headspace" to make sure they fit the chamber. It is much easier to correct little problems before getting to the range with a boatload of ammo that won't fit in a magazine or chamber in your rifle. Hopefully someone with a Dillon will chime in with tips for correct setup.

That sounds wrong.
I would screw the crimp die down against a cartridge with a bullet seated, NOT against the shellplate.
Once the die stops (by finger force), lower the press ram and add about 1/4 turn.
Then run the cartridge back up into the die.
Look at the crimp.
On a taper crimp die, you only want to see about a 0.030" long taper at the case mouth where the case is squeezed into the cannelure.
Continue adjusting the die 1/8 turn down until you see the proper crimp.

Remember that consistent case trim lengths are important to consistent crimps as a taper crimp requires the cases to all be the same length.
