Gee Preacher, you sound paranoid about someone misrepresenting your precious PDF.

So why did you misrepresent yourself when you first told us that the contamination at the point of this barrel rupture was ferrous contamination, but then later it magically became manganese sulfide inclusions? Is that an unfair question?

Too bad that you didn't post the first Southern Barrel Burst thread... where you came to such such totally incorrect theories about the possible cause. I told you almost exactly what Dewey Vicknair told you, but you couldn't begin to be man enough to admit that I was right and you were so very wrong. Instead, you ridiculed me for making an observation without metallurgical analysis, that turned out to be correct. But when Dewey made the same observations, you had no similar criticism for him.

Is that caused by excess acid in your soul or something?

Oh, sorry, I keep forgetting that when I point out your many errors, that is evidence that I have the acid in my soul. Also self loathing, and am in dire need of counseling and your disingenuous and hypocritical Bible quotes. Did I miss anything? I loved that last one where you wailed this from your blasphemer's pulpit:



Sounds something like Charleton Heston overdosing on estrogen! I sure hope that wasn't copyrighted. But I did attribute it to the disingenuous and clearly unhinged Preacher who wrote it, so it should be OK.

Is it time for your pictures of the little girl from Guatemala, or pics of your dead dog yet? Dead dog pics always gin-up lots of sympathy from the people that you still have fooled.

Oh yes... one other little thing...



"Possibly a large inclusion"???? Holy crap... A blind man could have found it by the braille method! Dewey Vicknair drew an arrow pointing to it and said, (as I also said) "Clearly, the failure initiated here." But what else would we expect from a self-styled shotgun barrel expert like you, who actually argued for days that lengthening the chambers of our vintage doubles could actually increase the barrel wall thickness at the end of the lengthened chamber?

re: the Herter's load. I looked in my files and couldn't find the source of the high pressure report. I believe it was from the 16g Reloading Group, but some years ago.

Here is another post from 16g.com
http://www.16ga.com/forum/viewtopic.php?t=22189&postdays=0&postorder=asc&start=0
"Tom Armburst test (of) Factory Herters 1oz #8s a couple years back Fps right around 1200, PSI right at 11500."

Obviously batches vary. The shooter gave me some unused factory loads which I did not send for pressure testing since the blow-up load was a reload. He did not send me any of his reloads.

re: the braze contamination below. It's complicated, and all I know is what the metallurgist and metallurgical engineer said. It should be obvious from the original thread that information and subsequent clarification came in over time.



150X SEM image of a contaminated region of the braze. EDX (Spectrum 1) showed the inclusions to be oxidized ferrous debris. The EDX are on the last page of the original thread



200X of the contamination (upper left) and oxidized steel (right) loaded with manganese sulfide inclusions



William: if you would please post your (real) name and email I would be happy to send you the report.

I can send you William's email if need be

I have it Steve, but thanks.

re: "burnt" steel. "Burnt" steel has specific metallurgic criteria.

Back in 1895 it was diagnosed visually. "Tempering Of Steel Tools" in the lower right
https://books.google.com/books?id=NkdCAQAAMAAJ&pg=PA20&lpg

Google "The Overheating and Burning of Steel" by Ko Tsun. It is on the internet as a PDF but I couldn't link it.

http://www.engineeringenotes.com/metallu...etallurgy/25931
Overheating is due to the solution of MnS in austenite at high temperatures, and its subsequent precipitation during cooling as fine particles (0.5 � 1.0 �m) of MnS at austenite grain boundaries.
In �burning�, formation of a film of sulphur-rich liquid takes place at the austenite grain boundaries. The damage is total and permanent, as the steels than lose their ductility and disintegrate during deformation.

If you can't dazzle them with brilliance... Baffle them with Bullshit! Right Preacher?

And pictures too! We must not forget the highly impressive pictures of steel that contains grain structure and inclusions... which you clearly don't understand.

There was no clarification that came in over time from you. There was a number of incorrect theories and immature behavior from you though. You still can't be a man and acknowledge that my conclusions about the probable cause of this barrel burst were almost exactly the same as the conclusions reached by Dewey Vicknair. It didn't take a rocket scientist or a trained metallurgist to see the obvious flaw and weak point in the barrel that ruptured. Anyone who had knowledge of brazing could use their brain to figure that a sound braze joint would help to support a section that was thin by design. Yet you felt the need to criticize me for advancing a probable root cause analysis without waiting for your precious lab findings... even though several other guys were giving their own incorrect theories. But being truthful wouldn't fit in with your narrative, and motivations, and sad need to discredit me, would it?

Manganese sulfide inclusions??? How very impressive ! Tell the folks here about the millions of Remington model 870 barrels that have manganese sulfide inclusions. Then tell them how Remington continued to use the same steel containing manganese sulfide, even after being sued over a small number of barrel bursts which most likely ocurred for causes totally unrelated to the steel they used. You would be a lot more credible if you didn't post such pure crap in a lame attempt to portray yourself as a shotgun barrel expert. Would it help if I posted some neat photomicrographs of bullshit?

By the way Preacher, why would you feel the need to ask for my full name and email address when you admit to SKB, the State Fruit of Colorado, that you already have it? Were you born being disingenuous, or was that an acquired trait?

Just giving you (another) chance to not be a coward William. Lots more images in the METL report which you might enjoy...and the metallurgist and metallurgical engineer would certainly appreciate your opinion regarding the "bullshit" they documented. Their contact infro is in the report - they were willing to use their names and even signed it. Credibility and professionalism.

So if a lost person, without hope, was reading your posts here on the Forum, do you think they would say "That Keith is sure filled with love, joy and peace. Wonder why that is? He says he attends a Catholic church. Maybe I'll ask him to tell me about Jesus"?

Little chance of koinonia for us William, but I really am praying that by the power of the Holy Spirit you can find peace, healing and restoration.

Now you know that's not what I asked you Preacher. I asked why you felt the need to ask for my full name and email address, when you then admitted to SKB, the Official State Fruit of Colorado, that you already had that information. Do you find Stevie's internet doxxing to be cowardly... or are you OK with that cowardly behavior? Pretty easy to see just who is being the disingenuous coward here.

And not at all surprising to see you once again hiding behind Jesus and the Bible again. What a fraud! Why don't you examine your own Christian behavior here... before casting stones?

And I've already seen what you've reported from the metallurgical analysis. The photomicrographs that you clearly do not understand add precious little to what was clearly evident to Dewey Vicknair and myself. I know you have this pathetic need to portray yourself as a shotgun barrel exprt, but you are never going to be another Dr. Oscar Gaddy. That would involve having intelligence and integrity.



To answer your question above... no, that doesn't bother me at all. But it sure seems to hit awful close to home for you.

Wow! I see your pal BrentD reading my post above. But BrentD says that he IGNORES my posts.

You Libtards are certainly a weird bunch. Do any of you have an ounce of integrity?

Thanks Drew!
