Palmetto: Sounds to me like the fine folks at Nosler "made" you some "short" brass.
It is MOST likely short in the neck length dimension ONLY!
Check on this.
The good news is they are consistently short and the neck tensions on your bullets should ALL be quite similar.
This condition (the similarity in brass length - neck length) will aid in accuracy and I see no real problem with your brass being 0.04" short as long as it is all in the neck.
Puzzling this condition, but not dangerous.
Neck sizing should NOT shorten your brass THAT much from the norm.
If you want more brass dedicated to that Rifle you may have to disregard these Nosler pieces and go with what ever brass you can get "enough" of for your neeeds.
If 50 is enough I would keep them and use them.
Mixing these definitely short pieces of brass with "normal" length brass will cause variances in neck tension and accuracy (if mixed in).
Best of luck with your 223.
Hold into the wind
