Brass Casing Issue at the Range


KSH

Recommended Posts

Looking for a explanation on what could have happened.

I don't think this could be a reload problem.

Bullet impacted -0 area of the target and no damage to the gun

what happened...

besides some one's Luckey Charms worked?

that case looks to me like the definition of the line

between 'safe' and 'incident'

hard to say why.

a little too much powder....

a set-back bullet...

an old case which can be fatigued or corroded.

and the last reason I am thinking will cause a fight.

hohohohohohoh

if you reloaded it,

you may want to look over your process

and check the usual suspects

Yes this is my reload.

This is my first incident in over 20,000 reloads in the last couple of years.

But it looks to me it was not fully cambered when it went off, also looks like a light primer strike.

How many times was that case reloaded if you know? That makes me think the case stretched over several cycles till it got thin and failed.

Not more than twice from me and I sort by head stamp

But a older case could have gotten picked up at the range

Hmmm so 4.5 is slightly above max listed. I'm guessing similar loads used on the previous loadings. So loaded fairly hot maybe this time the tolerances stacked to be slightly higher with a little set back or something and high enough pressures to just start to see the small pin strike right before it start flowing back into the pin hole. I'm thinking weak brass and everything went the wrong way. You didn't say what it was fired in so hard to tell the likely hood of not being fully chambered.

Hi

my advice is starts at you have evidence you are past the limit.

run lighter loads.

you may have reasons to ignore that.

so make sure your bullets do not set-back

make sure your powder drop is not giving you a little extra

consider running new brass

mostly accept that because you are running close to the limits

that you are working your cases harder and they will fail on the odd occasion.

I have been told that firing out of battery is never the cause of such failures

so I didn't mention it in my first post.

me... I'd check that too.

thems the usual things.

I've been shooting a TruBor 9mm major (165 PF) for eight years.

Got my gun back from gunsmith 3-4 years ago, and had three (3) of

those pieces of brass within a few weeks (I was doing a lot of shooting

during a two-day class I took, and a Major shoot).

The two pieces of brass that I found were BOTH WINchester.

Never found out the exact cause, but I got a lot of debris spit

out when the shots went off.

Posted it here on BE and lots of people thought gun fired out

of battery, but the gunsmith said that's impossible - it was the

primers or something else that I used.

I still have two of those pieces of brass by my reloader.

Good luck with it. :cheers:

It looks like it fired out of battery, because of the way it is formed.

Did you change your load after it happened?

Well, Ive noticed it here in this forum, its always some other things and NEVER the 9mm CARTRIDGE loaded to MAJOR. Just sayin' ;)

My concern here is not the "reload", but an issue with my XDM

The consensus here is that it is not an issue with my XDM.

You mentioned "-0" scoring area. Was this in IDPA? Are you trying to make "Major PF" for scoring in USPSA Open division?

I practice with IDPA targets

I was practicing Mozambique's when it happened, at the same time the next lane torched off a rifle. So I did not notice any thing different.

As far as the load, it is a load both my XDM and M&P like.

The brass that were BOTH WINchester.

It looks like it fired out of battery, .

I haven't changed Anything - to the gun or the reloads -

and I haven't had a fourth problem since then (3-4 years

ago). :cheers:

Never did find out what happened ... :ph34r:

The OP didn't say what power factor, but, from reading all the above I doubt if it was loaded to a major PF.

My Crony shows these at 1075

Which would be 133
