the shuemann informe. Problem number 5: Because of Problems 1, 2, 3, and 4 Type 416 Stainless is not a good material for sub-gun barrels

definitely not, two weapons of different brands were fired in parallel, if ammunition is a problem it should affect the other weapon too,

take some photos with a nikon d 7000, but they are not very clear I must get a good lens for close photos, it will take a longer time.

no place for a double charge in the brass

There is an internal mark on the stretch marks, product of the squib in your pistol?

The first thing to keep in mind is that SVI from the beginning rejected any possibility that the material was defective, without even seeing the barrel, hence my doubt and sent to analyze the material. It is for this reason that I request the quality certificates of the other 6 pistols.

the barrel broke, in the practice of unsheathing and precision to a plate at 25 meters, this was not a squib , I have it in my possession barrels, I will take many photos and share them with you,

I will not send it until Sandy answers the email that is a few post above

I cannot deny or assure if it is used a lot or a little, the calculation memory of the 416r for production pistols, the lowest factor the utilization factor is .29 resists three times the pressure, but for pistols the highest value factor is 1.02 factor of service, the material does not structurally resist open pistol pressure. I think SVI knows this perfectly because on its website it offers barrels of sae 4340 material, several times superior in quality compared to the aisi 416R,

My main concern is with my remaining pistols, my fingers and my face, there is no quality certificate and no pressure test, SVI does not show what pressure their barrels work, nor what pressure the barrels test since pressure breaks, It is very comfortable for them to say it is only a double burden and it is the responsibility of the athlete, but they do not display anything that certifies that it is a good product. I had to send them to examine the material to demonstrate that their barrels are not of good quality.

When that happens that you mention in the grooves of the barrels, there is a clogging mark. in this case he was practicing sesenfunde to a plate at 25 meters. all the shots went well even the one that explored the barrel the lead also hit the metal blaco

You read this pliss Schuemann_Barrel_Steel.pdf

I would like to know why there are many people who say that it seems that it is a double burden, but none assures it, much less mentions that there is evidence that this was really happened, the university report clearly says that the breakup did not occur Once, physically, no double charge enters the brass.

I always talk about the real thing, not what I believe or think, here in Chile in the last 3 years 12 SVI pistols have entered, today there are 4 broken barrels, all people have been denied a guarantee, the percentage is 25 %, the reason they say is always the same, our pistols are made of the best materials. if you enter their website they say that their barrels are made of sae 4340, and my reality is that they added aisi 416. therefore to say that they always use the same material (defective aisi 416r), it would be to ensure that SVI deliberately misleads people offering one quality on their website and delivering another. on the other hand there is evidence that the aisi 416r does not work for barrels used in IPSC or USPSA.I hope I can have the peace of mind that SVI in my other 6 pistols that are not yet used put a good material, copy the emails above, but that still does not happen I have been waiting for technical certificates for several months to review and I still have no news

apart from your opinion what tests do you have to ensure what you say?

of bronze?

the photos are at the beginning What evidence do you observe to believe that it is a squeb What evidence do you observe to believe that there is a lead behind another?

looking I found this Schuemann_Barrel_Steel.pdf

Take a good look at that fracture

If they have the original in January and rev 1 in March 5, I think you should ask for the quality certificate of the material with which it was made and the FAT tests (factoring acceptance test) they have the obligation to certify the quality of all the products they sell, only their word is useless

in a minor factor that material probably works well

Dear Friends The rupture of the barrel of the SVI MM31683 gun was due to the fact that SVI manufactured the barrel with a different material than the SAE 4340 that it publishes on its website, this gun was broken because they used a defective AISI 416r.
