I have a lot of .270 Win Remington brass which just completed eight cycles. Loads have been towards the warm end. Neck sized except full length resized for the first and the fifth firings. Trimmed to length at the fifth as well. Necks look fine and they pass the paper clip test. Primer pockets still tight. .270 brass is plentiful here, but this looks to me good to go. Where is the prudent place to stop? Thanks in advance.

What the hell is the paper clip test?

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.

When you finally get case faliure, doesn't that damage the gun? Or will you just get a squib round? Or something totally different?

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.

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.
