Rupture. Did not hurt.
I had a case rupture. New brass. Never had new brass rupture before.
WW 358 Win., 11 grains of Unique and a 180 grain cast bullet. Was fireforming 40 rounds of new brass.

Re: Rupture. Did not hurt.
Not nice! Hope you didn't damage the chamber with the hot gases spraying out that hole.

Re: Rupture. Did not hurt.
Looks like a flaw in the brass. I have never seen that either.
When thinking about it, How many millions of cases are made there just has to be one now and then that gets by the inspection process. I doubt that there was any damage done to the gun. Brass is trimmed short of the chambers neck length and thousands of them are fired without any damage to that part of the chambers.

Re: Rupture. Did not hurt.
My guess is weak spot. I was fire forming forty rounds. I just rattled off all 40 and then picked up the brass. I found it when I went to decap it. All this brass has previously been sized, trimmed, chamfered, flash hole deburred, primer pockets evened and sorted by weight. I've checked all the other brass for any sign of chamber damage and none found.pwl44m wrote:Any speculation, weak spot, only one, did U stop there,when did U realize. inquiring minds !

As a side note, the heavier brass did not fully fire form. The impact of this load was 11.5" lower than my regular load (100 yards) and all but two of the forty were in a six inch circle. If the 180 grain WFN bullets fed without catching I might have thought about working up a plinking load with them.
Kind regards,

Re: Rupture. Did not hurt.
Yea. It's the area just ahead of the web. When the case was drawn, there must have been some kind of a do-dag messing things up.----6Chuck 100 yd wrote:Looks like a flaw in the brass. I have never seen that either.

Re: Rupture. Did not hurt.
I HAVE SEEN THIS BEFORE. IT WAS A FLAW IN THE CASE THAT WAS PROBABLY VISIBLE; INSPECT INSPECT INSPECT CONSTANTLY INCESSENTLY. ANY LINES ON A CASE, ANY OFF TINY DIVOTS IN THE CASE, ANY ODD LOOKING SPOTS ETC ETC ETC ARE CANDIDATES FOR THE JUNQUE AFTER CRUSHING WITH PLIERS.

Re: Rupture. Did not hurt.
I'm sure you are correct. I probably should have seen it. As many times as I handle each new case I guess I got distracted.Terry Murbach wrote:I HAVE SEEN THIS BEFORE.

One of the reasons I am on this site is that I can learn from most of the people on here. Thank you Terry Murbach. I have not been inspecting cases as closely as I should. I have never had this happen, but that doesn't mean it can't happen.

Just think of the potential if it was a full house load. 60,000 psi vs the maybe 20,000 psi in the fire forming load.C. Cash wrote:Glad your OK!

Re: Rupture. Did not hurt.
I've never experienced a pinhole rupture like that with brand new brass, but I do sometimes get them right on the cartridge case cannelure after many reloadings in my Winchester .38-55 brass. It's usually easy to see them as they leave a sooty spot on the case, but I still make a quick inspection of the cannelures with a magnifying glass. I'm getting one or two for every hundred cases I reload. None of these pinholes have split the case open, but it's time for me to switch to some new brass.
