I have been reloading some mixed .223 brass and have found about 5 or 6 cases with split necks. Most of them are LC 89 brass. Should I be using a neck brush and some dry lube to resize or is it the nature of the beast on .223 brass? I have never run into this before on other cases.... I don't think the LC's have ever been reloaded, only once fired. Any help would be much appreciated. Thanks.

Are you implying the case neck splits are a result of your resizing or were they already split before you resized them? FWIW, in my experience case neck cracks in once fired brass while rare is not uncommon. If the split necks are a result of your resizing there's something not quite right. I do use some case lube on the inside of the case neck in conjunction with a carbide expander ball when resizing cases. Regardless if you use case lube, wet or dry, on the inside of the case neck make sure to remove it before seating a bullet. JMHO, 7zeor1. |

If I understand you correctly you want to resize the ones with split necks. If that's the case don't do it. Smash the necks and throw away or recycle.
If you are asking is it just part of reloading then yes part of life. Annealling helps reduce split necks, but if overheated you could get soft base which is real bad. Anneal before sizing. Mil brass tends to split before commercial brass all things being the same, FYI. |

Some cases split right off, others the primer pocket will get loose first.
Luck of the draw. You should be lubing the case necks before sizing, and remove after sizing. I use Dillon spray lube, cases in a box, a little spray gets into the necks. After sizing I tumble in plain corn cob to remove the lube. |

I geuss I should have made myself more clear.... sorry...I definately will discard split cases. I have a carbide expander ball in my die but I have not used lube on the inside of the necks. I will ceratainly try that and see if that helps. I made my first batch last night and used a C.OA.L ay 2.260 and they barely fit in my Colt magazine. Is that about right?
