Ten-X rounds cracked brass

Recommended Posts

I purchased a large lot of commercially loaded  BP ammo from a fellow club member that time caught up with. All of the ammo was at least 10 years old.

Most of the ammo was Black Dawg Cartridge Company but a few boxes were Ten-X brand.

 

Been shooting the ammo at bigger matches and have had zero issues with the Black Dawg  ammo. However the vast majority of the Ten-X ammo cracked the case when fired.

The cracks are all in the center of the brass and run the lengthwise. None extend to the case mouth. 

All of the brass has a StarLine headstamp. No extraction issues and all were fired in a Rossi 92 that I have been shooting for years. 

 

I suspect the powder attacked the brass some way but no idea what powder these were loaded with. I checked the box and there are no date codes anywhere that I can find.

 

Anyone else experienced something similar?

 

Kinda bummed that I can't recycle the brass

 

Pics of the brass and box below.

What does a loaded cartridge and also the fired primer look like?

 

Oh, and may I be the first to say, "Nice manicure". :D

Not sure I have any unfired cartridges. Here is the headstamp of a fired case.

Nice, I was wondering if the cartridge may have been bulged when it was loaded or if the primer might indicate a pressure spike. Thus ends the extent of my complete lack of knowledge. 

Just to lessen what I don't know, does black powder substitute affect brass?

I've had this happen to many Starline cases on their first loading.  They had been loaded with Triple Seven and stored in dry conditions.  Since they were bought with a door prize coupon I did not inform Starline.  The cases that survived their first loading were good for many reloadings.

You might check the diameter of the bullet used.

If the bullet was under sized, say .356" or .357" that would require sizing the case down to get hold of the bullet.

During firing, the case would expand faster than the mouth where the bullet base is crimped.

This quick expansion could crack the case below the bullet and above the case solid base.

 

If you have fired all that ammunition, there is nothing to fix but toss the cracked brass in the scrap bucket.

 

Unfired ammunition coulpd have the bullet pulled and then resize the case and put an appropriate bullet diameter in the case.

TEN-X will reload brass that a user will send to them.  Maybe all those pieces of brass were sent in for reloading by the original owner and who knows how many times they had been reloaded.  I get those exact splits on some of my .45 Colt brass (all of different headstamps) that I have been reloaded many times.  When I resize and deprime my .45 Colt brass, I take a quick look at the "good" ones.  If I see what looks like cellulite on the side wall of the brass, I don't reload it because I think that is a sign that it will fail soon.  Near the split in your picture, it looks like the "cellulite" issue that I am talking about.  That is just my theory.

Wasn't just a few, more like 90 plus out of 100. Didn't notice till after wet tumbled.

Had the same exact problem with a batch of Starline Brass.  Splits on the side of the case that did not extend to the case mouth.  I never believed you could get a batch of "bad brass" but now know you can.  I called Starline and they said the brass had not been properly annealed when it was formed.  They sent me some new brass based on what I noticed was the failure rate.  I should have sent the whole batch back as the cracking was less frequent but still occurs with that batch.

I had a lot of split cases in ammo that I had loaded years ago with Clean Shot. I had no problem when the ammo was fresh.

Wonder what the before and after firing case dimensions are? 

Did this happen in just one gun or?

OLG 

 

I'll get the before / after case dimensions when I go back out the my loading shed.

 

All rounds were fired from the same gun. Up until now this has never happened in this gun.
