Hi all, Not sure if this is a bad batch or just poorly made in general. After a big shoot in the weekend I found that a majority of these Winchester X .223 rounds had splits in the necks. I guess be aware if you have these or are possibly looking to purchase. I will not be shooting Winchester .223 anymore personally. Anyone else had this recently? Attachment 21463
Ouch. What load were you running ?
My observation is that some commercial ammo suffers badly from the galvanic corrosion between the dissimilar metals in the projectile and brass.
Considering this I would say most are assembled with lube in the necks to avoid this, but some ammo no doubt gets assembled "dry" in the neck area with the potential for galvanic "welding" to take place.
When disassembled by hand the projectile comes out with a loud "crack" as the corrosion lets go, perhaps under the extreme stress of firing this is too much for the time hardened brass to handle and as the corrosion lets go unevenly the neck cracks.
I’ve seen this in Hornady .223 too. Craig had a batch of it.
Not good.
Shooting an AR15 or AK action?
Shooting Ar15. These were all brand new from the box. Never reloaded. That's the surprising part. Do you think this would have affected my barrel?
Very high chance of Little to no damage
I wonder if it's worth going back to the shop I purchased them from and complaining. Would seriously piss me off if my brand new ar15 was damaged because of this ammo. GGrrr. Thanks for the comments. They are all helpful :)
Interesting, didn't notice any split necks from the box I tired (64gr) but it looked quite inconsistent to the eye and didn't group well from my rifle.
this was the 55gr jacketed soft point. Not really sure what to use now. Will have to do some more research. :S
Oversize chamber?
Yes, take them back. Could be just a bad batch from Winchester.Quote:

Might have not annealed it properly, or at all or something. I've heard of Federal/American Eagle doing this as well.
I've also had PMC brass do this.
I've even seen cracks in new PMC brass before it was fired.

I bought about 4k rounds off a dude in Waitahanui in Win 223 which had been thru a spray gun but after annealing and SSM cleaning it was great brass to load. No issues ever.Great believer in annealing. Do it to all brass even new.
P38 we reckon PMC is the best brass we have ever used.
I reckon the Sellier &Bellot ammo is pretty good. Had good results with that and brass seems good. :)
I have always found the fiocchi 223 goes very well in the Nea15 and the Remington m700 I have used both their 55g fmj and their 69 grain load with the sierra match kings.
