Reshoot Posted July 17, 2013 Share Posted July 17, 2013 I discovered this piece of brass, during my post-tumbling inspection. The round would have been fired , here at home, sometime last week. That Taurus 24/7, that blew apart in my hands several years ago, is now fresh in my mind again Link to comment Share on other sites More sharing options...
Zoomy Posted July 17, 2013 Share Posted July 17, 2013 I have seen "kabooms" twice in the past 14 months. I now spend an extra second per round to inspect each case. Glad you found it before pulling the trigger on it. Link to comment Share on other sites More sharing options...
midget Posted July 17, 2013 Share Posted July 17, 2013 Wow...damned good thing you caught that... Though I'm willing to bet that when you tried to resize it, it would jam your press... Link to comment Share on other sites More sharing options...
perazzisc3 Posted July 17, 2013 Share Posted July 17, 2013 does anyone think the brass quality is poor or maybe excessive pressure? Link to comment Share on other sites More sharing options...
Poppa Bear Posted July 17, 2013 Share Posted July 17, 2013 does anyone think the brass quality is poor or maybe excessive pressure? Looks like a well used piece of brass. I have 8 to 10 K on hand so they get cycled through the press slowly. It would take me about 50 to 60 K rounds before I would worry about the same piece coming through 7+ times. The greater likelihood is I will lose it before then. This piece looks like it has been reloaded many times and the two weakest areas are the mouth which tends to split lengthwise,(the most common one I see) and the area just above the web/extractor groove which cracks at the groove.

Flexmoney Posted July 17, 2013 Share Posted July 17, 2013 I like to rattle the brass around a bit, pouring back and forth from one hand to the other. Cracked brass will generally give off a different and distinct sound. Link to comment Share on other sites More sharing options...
Poppa Bear Posted July 17, 2013 Share Posted July 17, 2013 Brass is much like a bell, when it is formed into a quality case it has a light ring to it. When it cracks it turns into a dull thud. Part of my work involves chimes like the wind chimes you see people hang up just bigger. When whole they have a great ring, even a small crack will create a dull thunk when struck.

Reshoot Posted July 17, 2013 Author Share Posted July 17, 2013 One thing I am confident of, there was no apparent sign anything was wrong with this piece of brass, when I loaded it. Ever since that Taurus came apart in my hands, I have inspected each piece of brass as it comes out of the tumbler. Then, I inspect again after the round it loaded. Has this piece of brass been fired too many times? Well, one too many times for sure! When I first started competing, I marked all my brass and tried to recover it. But then, it was all new brass at that time. I drifted away from that but, now find myself reevaluating. After all, I feel just plain lucky this round did not blow my gun apart. What would you do in my position? Seriously, I'm asking! Here's the load, BTW: Bullet: 155 gr. MG FMJ FN Powder: 6.6 gr.

Cracked brass will generally give off a different and distinct sound. This. I also find it is much easier to hear than to spot. When I'm collecting my spent brass at the range I always collect a half dozen pieces or so and shake them around in my hand before dumping them into my brass bag.

Tackman11 Posted July 18, 2013 Share Posted July 18, 2013 It's a good reminder for me to check all my brass. Thanks Link to comment Share on other sites More sharing options...
kamikaze1a Posted July 19, 2013 Share Posted July 19, 2013 When I am policing my brass at the range, I jingle a handful in my hand before dumping in my brass bag. If there is a cracked shell, I can tell by the sound right then and there and weed it out. Link to comment Share on other sites More sharing options...
Kyreb Posted July 19, 2013 Share Posted July 19, 2013 Wow! Glad you caught that. 40 brass seems so much more likely to be problematic than .45 or .9mm. Link to comment Share on other sites More sharing options...

Rideandshoot Posted July 31, 2013 Share Posted July 31, 2013 Sorry if this is a dumb question but what would outcome be if this had been fired. More specific than kaboom:) Link to comment Share on other sites More sharing options...
kamikaze1a Posted July 31, 2013 Share Posted July 31, 2013 Powder would ignite, hot gasses would escape very rapidly through breech in brass, mag would blow out through bottom, hot gasses would blow through every opening, shooter would crap their pants and everyone around you would be unhappy...

fuentesd99 Posted July 31, 2013 Share Posted July 31, 2013 (edited) Your load sounds good to me. I use a Rainier Ballistics 155FP with 7.0 of AutoComp at 1.130 OAL for a 179PF. May I ask why are you loading so short? Edited July 31, 2013 by fuentesd99 Link to comment Share on other sites More sharing options...
Reshoot Posted July 31, 2013 Author Share Posted July 31, 2013 Sorry if this is a dumb question but what would outcome be if this had been fired. More specific than kaboom:) In the case of My Taurus, it blew the magazine out of the mag well . . . magazine parts and bullets scattered as far as 8 feet. Parts of the frame, on the right side, blew out but did not break my skin (polymer frame). I could not feel my hands for 15 minutes, and did end up with bruises. Left side of the frame was cracked down to the trigger guard. This happened here at home, with son-in-law recording. I dropped the gun but then, I could not feel the gun in my hands anyhow. I have video and pictures somewhere. I still have that piece of brass, and as best we could determine, it was the cause. I hope to never have another such experience! But, when I found that piece off brass, I posted here, I realized it cold have been the same result. Oh, when I called Taurus and explained what happened they told me to send the gun to then, and they would take a look at it. Four weeks later it was returned, completely rebuilt at no cost to me. I believe the gun was 4 ~ 5 years of at the time. Link to comment Share on other sites More sharing options...

jmbaccolyte Posted August 1, 2013 Share Posted August 1, 2013 What do you mean by it "works"? I thought the longer you loaded a given recipe, the milder the pressure spike became until of course, the bullet ogive started to touch the rifling lands and caused the pressure to start spiking again.
