We all know that most chambers are cut for 5.56mm NATO. I've yet to load my first .223 round. I do load for everything else and know all about partial sizing and setting back the case shoulder. But this is for an AR-15, so I can't check it by feel.
Do you guys just full length size in .223 dies and bump the shoulder back every time? I wonder because if the NATO shoulder is slightly longer, brass will get worked quite a bit.

Chamber is the same it’s the leade that is cut deeper if I understand correctly. I use a Hornady case comparator and set the shoulder back 2-3 thousandths, just so it chambers easily. https://www.midwayusa.com/product/1012743827/?pid=479704

You'll quickly learn there's no such thing as loading for a specific AR. You're loading for all 5...10....maybe 20 ARs you'll end up with. So, yea, resize back to spec for AR's.

Just save yourself the trouble, and fl size them. And yes, you'll end up with more than just one..

I use a cartridge gauge, Lyman in this case. Checks for proper sizing and case length. If it fits in the gauge, it fits my guns, so far at least. A pocket machinist’s rule easily helps check that the case isn’t sticking out over the steps at either end; just slide the edge over. If a case is sized too much, the corner of the rule will catch on the edge of the minimum step.

Cartridge dimensions are exactly the same.
Full-length resize, but try not to move the shoulder more than a couple mils. The less you move the shoulder, the less work hardening, the more reload cycles before cracking. I don't anneal. I reload for 2 ARs, one carbine-length and the other rifle-length gas systems.
I know that the first time I FL-resize range pickup brass I can be moving a lot of metal around. But on subsequent load cycles as little as possible.
I use a Brass Goat.

I set the redding dies up just like the redding directions say and resize the brass, trim to length, load the bullet to just shy of magpul magazine length.

I measured all my fired cases and was surprised at the difference between guns. Had a LaRue that was loose as a goose on headspace and a Krieger that was pretty tight.
Wound up selling both of those and keeping ones that fell in line with the rest of them. Keeping AR brass separated is a pain I got tired of dealing with.

Spend the money for a set of calipers and the Hornady comparators. The brass I resize for the AR's and NATO chambers won't fit in a standard .223. They are 2 different animals. Keeping the brass separate is a pain in the rear but I have the time so I do it. Or you can do like TRW did as sell the ones that don't fit your needs. kwg
