Go till you see pressure signs or any other case failure. THen get rid of the whole lot. At least thats what I would do.

If it looks good, use it. All upside, no downside.

You are most likely going to have a neck split which is no big deal. If you haven't been overworking the brass (which I doubt you have been if you have 8 firings) you shouldn't have to worry about incipient head case seperation which is a big deal. Since they all passed the paper clip test, I'd load them up another time or two then toss them all.

Generally the neck and shoulder will split or the body will separate, or the primer pockets give out. Won't hurt the gun, but a case separation is a pain in the neck.
You might consider annealing those cases (neck and shoulders). Then keep shooting them until they are done. That might be 30 reloads. |

Sharpen end of paper clip. 
You can feel if case is starting to seperate. |

I had a .17 fireball split I opened the bolt and the brass was split in two . It didn't shoot any different. Looking at my brass the other one started to split but stayed together. The contraption below is how I removed the top of the case. I think there were six reloads including once fired as a .223 case.

I have 30-06 cases with more than 12 firings. When one splits I figure its a just weakness in that particular casing, which is often the case because the whole lot usually continues for quite a few more firings.

had guys get 12+ firings out of brass. depends on the brass really. many will just keep going until they show a split.

You are confirming what I thought. This lot should be good for at least two more cycles. Split necks are not a big deal, but I don't want to have to deal with case head seperations. I hate to throw away fire formed brass if it's still GTG.

Here are some LC cases that went for 10 reloads and still look good, and these were fired from a M1A, the one on the far left is once fired

anneal them, full length resize them, then do the paper clip test again and reload them some more

I would respectfully disagree that case head separations (CHS) are a big deal. I find that they are a product of the gun, either it has CHS as a common failure mode, or it doesn't. I only have one rifle, a Savage 99, that suffers CHS, and I have had maybe half a dozen cases fail this way in that gun. It was completely uneventful each time, and I never realized there was a problem until I saw the case. I have never had a CHS in any rifle other than the Savage.
The only case failures that are a big deal are case head failures, which don't seem to be caused by use, but rather defective cases. I have never seen one of those. |
