A buddy of mine has given me a pile of 1F .223 range pickups from his local range. Nearly all head stamps are Federal Cartridge with the odd Lake City. I have mixed it in with all of my 1F Fiocchi to be reloaded.

After tumbling, and FL sizing, I have started to trim them to length and I'm noticing that almost ALL of the FC stamped brass measures under 1.750" before trimming - some up to .008" short!

This leads me to believe that the necks of this brass are short and out of spec from the factory - after full length sizing the shoulders should all measure the same, correct?

I have loaded plenty of .45ACP, but this is my first foray into reloading .223rem. Is this something I should be concerned about? Can I load it up and blast away?
 
Federal brass is soft. The primer pockets enlarge and puke primers. You'd be better off to scrap the brass.
 
I would just load it and shoot it. It will grow anyway and might get you another firing before the cases need trimming.

Brass sometimes shrinks on the first firing, caused by the new case blowing out to fill the chamber. .008 short is absolutely nothing to worry about, it just means you can maybe get an extra reload or two before you have to trim.
