Neck splitting

[92xj]

If you had 20 loaded rounds and just went out and shot only 10 of those rounds and 3 of the 10 had split necks after shooting, would you shoot the remaining 10 rounds? Say the group is great, at .6", per each 5 shot group.
Cause of the split will be too many resizings without annealing.

If you want to save the brass I'd pull the bullets. If it's not that expensive of brass, I'd shoot them.

I would not.

I lose 10% every reload with my .25 WSSM. It's the only caliber I have that neck splitting is an issue. I have not annealed any of my brass, don't want to screw it up....lol

Do not care about saving the brass.  Would rather shoot the good groups own last time and start with new brass next loading.

I would not.

Why not?  What would/could be the consequence? 
Side note, I did not inspect the brass during my ten round shooting, only noticed once home.  So, the 3 that split could have been anywhere in the lineup.  No issues were noted or felt during shooting.  Inspected gun and see no damage or issues currently.

If they split from the top of the neck down them maybe too many de'burrings inside and out and the material was getting a bit thin.

I would dump them, it's only a few rounds and if the neck is splitting from resizing then the case head might not be too far behind. 

I had a similar issue last week, out of 30 brass I had two that had the case head half separated (didn't fully separate but you can see through it on the split part). 

If they separate, you could damage the chamber by gas cut as well as have a jammed top half stuck in the chamber.

Probably just expired brass, and since annealing softens the brass, there for extending its life, 2-3 firings then anneal or expect premature failures.

Only out of an abundance of caution. I would begin to doubt my loads....what did I miss....etc. it's not like your blowing out primers or locking up your action but I would just prefer to avoid any type of case failure when I or anyone else is putting your face next to a contained detonation.  I've got an uncle that lost an eye in his youthful years being stupid with 22 ammo. If you are loading and annealing brass your are imo clearly experienced enough to know what you are doing and not stupid but I would simply say ok this brass is done,  break em down, and start a new cycle of brass.
