Split Case?

[Sharpie]

Pure drivel.

No, not really. I did say that "The Lee Classic loader is a very poor tool, in some ways."

I'm prepared to justify that, but expect a lot of hate from sentimentalists who like to reminisce about them. How many of you actually use them, be honest. There are better ways.

Can‘t really follow you on the Lee Loader issue. Especially a F/L resize would make this damage much more likely than a simple nick sizing.

I think not. But @Spikelet has explained that this either happened first time with factory ammo, or on his first reload of that brass. So difficult to explain, other than sometimes things go wrong. Probably not the Lee Loader's fault, but there again I could also speculate as to how it might have been. Which probably wouldn't be constructive.

Yes, it's either from my initial batch of 8 that I made up to test my load or its from never previously reloaded factory ammunition, that I accept I stupidly mixed up.

Again, I would be having a look at the chamber.
That is a "Hot" split, not just a crack / break, magnifying the pic you can see where the molten case metal has initiated the crack.

I've just started to try reloading and as I went to examine a used case I spotted this split case.

I have to admit I'm not sure if this was a once used factory Hornady case a case or one that I've already reloaded, if so the load was 42gr of Ramshot Hunter and a 75gr Vmax. Loaded using a Lee classic loader.
I've been very cautious and double checked my loads, which at 42gr is slightly under Western Powders suggested weight.
Is this likely to be just a badly formed case or am I missing something, any advise would be much appreciated

Hmmm. I have not encountered a split like this though from wHat I can see it could be a result of incipient case separation.
ICS more usually results in a failure just ahead of the case web and can be spotted before case failure by the presence of a fine line/ring again just ahead of the web. It is sound practice to run a bent sharpened pin or piece of metal (Paper clip) up the inside of any case before reloading. The attached pics show several examples gathered by me over many years.
PS
Do not start below manufacturer-provided data! If you are uncertain start at the minimum and work up slowly in small increments until you find your dream load.

Yes, it could be as simple as just an inherent flaw in the brass that blew through, initiating the split. As I said, sometimes these things happen. But could be all sorts of other reasons. Either way I'd bin those cases and start again.

I would just load up and keep shooting.

 

[Spikelet]

Just a quick update, tried the paperclip test, couldn't feel an issue but just to be sure

Interestingly there are actually two cracks parallel to each other.
I'm borrowing a snake camera to check the rifle and have taken note of the underloading advice

Looks like a crap case ! but watch out for light loads they can be killers as they can plug the barrel with the bullet and force your chamber into a grenade

Totally get it, I'd have to say I was only fractionally off the minimum and whilst I haven't checked the exact velocity the loads performed extremely effectively.

Don't worry, a start load will be absolutely fine. Even quite usable. Some here can get their knickers in a twist about imagined ways about how such loads might go horribly wrong. They do not.

Always interesting to see if the chamber is now gas cut, but it will more than likely shoot just as well as before.

How about running a book.

Drama queens verses the non eventers.

My £10 says there will be nothing wrong.

I’m not so sure, I think the fence sitters may take, or maybe not.

Obviously that is a completely different case Showing (or not if it is faked) something different. Got any more to show us ?

I suspect a wind-up from you. If so you've had your fun.

If I have misjudged you, well, I apologise in advance.

How can you tell its a different case?

 

[nCognitos]

I've seen the same with 6.5CM S&B factory rounds on first firing. I doubt it was you, most likely a weakness in the brass

Are you blind ?

Does this:




Look anything like this ?



I call it BS. @Spikelet All of ten posts to your name (seven being on this thread). Since you joined this forum on April 8th. Unless you have some other explanation.

Still, you have managed to get a few jumping around in response.

Looks like our resident 'expert' @Sharpie comes to the rescue...

Outside picture, inside/Cross section pic... what's the problem? Pics taken 11 hours apart, plenty of time to cut the case in half.

The mystery deepens and well done for assisting with the sectioning and photo. Assuming that it was you who was there and know about that.

If you were there, then clearly that piece of brass was seriously bad. and so might the rest be. Though still not quite clear at what I am looking at.

My mind is not closed, but I have never seen anything quite like this before, and hopefully never will.

As I did say "If I have misjudged you, well, I apologise in advance. "
