So when I sized with my FL Die I turned the die all the way down until it touched the shell holder when it was in the upright position. Then I then put the die 1/4 to 1/8 more down like the RCBS Manual said.
If I continue to reload like the manual states will I have a major headspace danger issue, or am I just going to decrease the lifespan of my shells? I'm going to be using this ammo in different 223 rifles too.
I'm just confused on whether not this is a critical step. it seems like they would of included it in the manual normal reloading steps if it was a must.

Iaanguiano:
Welcome to Handloads.
The way you just discribed setting up the die for full length resizing is recommended, especially if one is going to use the reloads in different rifles.
In technical terms, there could be a slight amount of headspace in a chamber that was reamed just a little long. You should however, not be in danger of excessive headspace unless the chamber was reamed excessivly long.
You will find that your cases will have a shorter life than if you had loaded each rifle with its own loads and used a neck sizing die to prevent excessive stretching.

What Jack said..
If any of those rifles are autoloaders, you may find you need a small base FL die....
Actually your are best off doing what he recommended and dedicate batches of cases to each rifle. Nothing more frustrating that getting out in the field with shells for the bolt gun and finding out they wont chamber in the AR, or vice versa....

And don't let the RBCS instructions get you to thinking wrong. By adding that extra 1/8 to 1/4 turn, you are not changing the headspace. All you're doing is making sure the die sets down firmly against the shellholder. As long as this is happening, the only way you could change (shorten) your headspace would be to file away the bottom of your die. Otherwise, the distance from where the shellholder meets the die to the internal shoulder of the die will be unchanged.
If your die didn't seat firmly (or consistently) against the shellholder, then you could get a longer headspace.
Oh, and welcome to the forum.

Is it possible for you to keep the brass you fire from each .223 gun separate?
Yeah....I know that may be impossible....but I'm just askin.

Hey Laan
That ajustment is a so your single stage press has a cam override to insure the caseing goes all the way in the die.Not holding back a little when there is a resistance in sizing. You want to make sure the shellholder makes contact with the bottom of die + when casing is being sized. It does not under size your caseing. Autos and levers rifles need small base die sizing

Thanks for the welcome message 
This totally makes sense now.. You guys are great. Hopefully the FL sizer will be enough for my AR-15, if not Ill go back and buy a small base sizer.
Anyone use the x-sizer dies? RCBS even has a Small Base X Sizer Die.

Hey Laan
Its not a 1/4 turn or 1/8 turn .Its 20-30lb overcam at end of handle on your single stage press when the shellholder meets the sizer die or trim die.I use my thumb pressure for this . On seating, the seat die they setup differently

Just a word of caution, don't mix brands of shell holders with dies. I have a set of .308 dies that will FL resize with excessive headspace due to a different brand of shell holder. Nothing worse than pulling out a case that has a ring cut half way around the case from stretching...except getting the front half stuck in the chamber (thank the Lord I caught it after the fourth round and stopped).
