Have you seen something like that before? First reload on 270 federal brass. Was annealed ect. Never liked Federal brass… I’m reloading for a mate who has hundred of them once fired.
Case was well lubed, feel while resizing was normal no excessive force ect. It split and the neck stayed in the die. Was not even stuck it felt off afterwards.

Is it the only one, or was there several like it? I've never had any issues with Federal brass, not likely to be the fault of the brass. Have you checked the setting for the sizing die? Are you full length resizing or just bumping the shoulder?
Only one mate, reloaded probably 80. I'm full length sizine.
IMO, brass is only once fired unless I’ve shot them myself.
Take someone else’s once fired claims with a pinch of salt.
That's not a split neck mate. That's when the brass has gotten too hard and you get a vertical slit appear going down the neck.
You've managed to rip off the entire neck so looks to me like they were over-annealed. Soften them too much and they loose all their strength.
The guy doesn’t reload, it is 100% once fired.Quote:

My guess would be it happened only after the sizing stroke and when the expander plug was pulled back through the sized neck. Either the neck's interior surface wasn't lubed or was insifficiently lubed. Mostly this would cause the plug to bind and take noticeable effort to pull completely through. It's rare for neck separation to occur in such instances so I suspect your comment about long term poor storage of the brass probably has merit.
Anyway, better to lose that substandard case now rather than when being shot.
A bit of column a, a bit of column b. The blow torch until you get a slight glow method isn't particularly precise. Different brass will react differently too. You could well be over slightly doing it slightly.Quote:

I’m way more accurate annealing in a pitch black room and stopping at the first sign of cheery red. The difference between brass is usually a second or two max depending caliber and brand of brass.
You dont need to anneal in the dark. Probably unwittingly over annealed. The force of the die has pulled the annealed part of the case away from the bottom.Quote:

Have used plenty of FC brass over the years & in a heap of different calibres and had good results. Only time I’ve seen something similar was “once fired old brass” (243), probably stored 7-8years or more. Annealed the rest of that old brass & the problem was resolved.
Ive NEVER annealed.....have some .270 brass with maybe dozen loads through them...Ive seen case seperation down in web area ,also seen it in .223 but never what you have shown....at all.

I would suggest that this is one of those unusual failures. It would be nice to find out why but in actual reality it probably won't change anything with the rest of the brass even if you did know. Personally I'd give the rest of the brass a good once over, bend a piece of wire into a small hook and slightly sharpen it and have a feel inside the rest of the brass for any other cracks or weirdities.
Hard to tell from a photo and not being able to move the case around to play the light over it...Quote:

He will just have to get descent brass or keep shooting factory pills I can’t be fucked dealing with the consequences of a round failing on firing.
oh man can I now relate to that comment.....Quote:

I'm now annealing all brass I buy or range brass I get prior to using.
In and of itself, the 10-12 years is not a factor. A lot of ammo is still functioning fine after 60+ years. Especially milspec, some of that is over a hundy.Quote:

Have had batches of factory rounds that split on first firing, some calibers are really bad for this.
