You need to trim after sizing. Sizing changes the case shape (of course) and will effect case length.
Lots of .223/5.56 brass has crimped primer pockets.
You need to remove the crimp, different ways to so it, as always faster cost more.
I Had a Hornady lathe type trimmer, it works well but is slow. Bought a Worlds Finest Trimmer (WFT) you chuck it in a 1/2 drill and go. Much faster, money well spent IMO.
Now I don't even measure .223 brass, I just run it all thru the trimmer, if it needs to be trimmed it gets trimmed if not it doesn't. Faster that way than measuring.
