Dings in necks of .223

[nucular]

I have been reloading other cartridges for a while but am just now starting .223. I cleaned up some brass (some of mine + some range pickups, various headstamps) and almost all of them have a single nick/dimple in the neck area. Just curious if anyone has seen this or know what causes it?

I have had some dimples in the shoulder areas caused by hydraulic pressure when using too much lube on resizing. Never had any in the neck.

Were these ones you shot or range pickup?

It's both and I'm not sure which is which. Next time I'm out I will use the brass catcher. Most of the brass was mine and it was old winchester white box stuff - no reloads. I was wondering if I had some sort of imperfection in my barrel but I don't have a scope to get in there and look around.

It is probably a good idea to inspect the chamber area, but if there was something there causing it I would think it would be a line going all the way up the neck upon extraction.

I am sure someone with more knowledge will chime in.

If I were to guess it's from the brass hitting the deflector upon ejection

have those been resized & trimmed?

Impacting something upon ejection. They’ll load fine.

no, just tumbled to clean them up.

Likely from the deflector, but in any direction they are totally safe to load and will simply fireform to your chamber. The minimal dents will not impact pressure or loads from capacity.

If the little dents extended into the neck, simply running a mandrel through them will push the imperfections out of the inside, just will still be visible on the outside.
