@lou45… had a similar experience on one of my deltas. Not as bad tho. Oakley's saved my face and it blew the base plate off the Tripp mag (welded base, BTW)

Do you have a delta emblem scar on your hand? Because that would be bad ass

I was wearing OSHA approved safety glasses when that happened so needless that was a good thing. The rest of the right side of my face from the center of my nose took a number of small pieces and finer particles of brass that embedded into the skin; hadda' pop the festers that the finer embedded particles created about a week later to get them out. The bigger pieces that were visible I pulled out with tweezers. One piece embedded in my into the gristle right in the front of my nose; that was hell trying to pull that piece out without it breaking off and leaving part of it stuck in the gristle.

The emblem in the hand??? Naahhh, I just rubbed it out..........................many times.

I think what he is saying is if the barrel wasn't rated for plus +P, maybe it was because of the lack of case support. If you bought a barrel that's isn't rated for +P with the intent of shooting +P that's on you.

That's what I think he was trying to say anyway.

Yep. Pretty much.

I get it. The only way to get that would with a ramped, fully supported barrel. That would require machining of the frame and so on. The standard barrel, such as this one but properly throated, would be okay for +P being the throating isn't cut as deep.

From the brass appearance I could run standard loads through the pistol with the present barrel it but it still wouldn't be right. I may until I get a Kart barrel to replace it.

Shot a box out of my M9 yesterday... :ohnoes:

without fault or anomaly. The lot # was 14160024. The slide stayed intact, no injuries to report, and upon inspecting the brass, no defects were noted.

I also shot a box of ZQI 5.56 and 7.62 (at $9.97 for 30rd and 20rd boxes of each, it's the cheapest local brass cased ammo in these calibers that I've seen) out of my M&P Sport and sub $300 Rem 770 (cantaloupe groupings @ 100yrds :brows:

). Each round went bang and penetrated BOTH paper AND clay!!! :shocked:

Won't hesitate to buy again. :thumbsup:

I have shot it out of my p226s, g19, and 2022s without incident.

That's been the plan s

They had a decent amount of ZQI at the North East Walmart today. I decided to get another box since they had plenty. Given it is $12.97 a box, accurate, more pop and about the cheapest brass 9mm there I will be shooting a ton more of it!

Ellicott City WM had a boat load of various 9mm, including several boxes of the ZQI.

Don't know if you get down that way, Lou.

I also frequent the north east wally world! Ammo shelf has been looking good lately! I've shot this stuff out of my 92FS without incident.

ZQI sent an RMA for the balance of the ammo and the fired cases. They were cool about it and even sent me a free box of ammo.

Before I got the return package I fired 4 rounds of the ZQI in this hot box out of my M&P which has a chamber which is fully supported but very loose. The primers show a good bit of wiping from primer extrusion. The case webs expanded approximately .004" to .005" greater than WIN Value Pack cases expanded. That is pic #1..

Additionally, I fired six rounds of Federal HST 147 grain +P and another box of Winchester factory 115 grain FMJ out of the 1911 as well. No abnormal pressure signs were observed. So the barrel will support a +P load. Pics #2 & #4.

A comparison pic of the primers signs of the ZQI and a handload (+P+ head stamp) fired from the M&P. The M&P causes a tear drop or triangular shaped extrusion on the primer. Pic #3.

Primer indicators of the ZQI, Fed +P and WIN fired from the 1911. Pic #4.

So now you know that 1911 needs a rework.

Wow. The whole thread is on this. Just posting for informational purpose.

Actually, I know the gun is safe with standard and +P 9mm ammo.

atblis · Sep 27, 2014

Maybe I missed it, have you chronoed this ammo?

MdPrep · Sep 27, 2014

Is it the way the ammo is being fed/ejected that has caused the brass to warp like that? Definitely a scary issue. My untrained guess would have been ammo, but seeing some here believe it to be the firearm has my curiosity on how the firearm would make the brass bulge that way.

Fordracer2082 · Sep 27, 2014

I bought 100 rounds of this to try before I found this thread. I was using it in a glock 23 with 9mm barrel. I fired 240 rounds of other ammo including 20 +P. With out a problem . On my 3rd round of ZQI 9mm nato the case bulged and locked up my pistol. Had to run a rod down the barrel to get the action to open again. Had the range dispose of the remaining 97 rounds. I will not be using it again.

I am going to buy a box and see what it does in my AR. It tends to be pretty rough on the cases.

Shot some of this out of a SCAR couple of weeks ago...no problems to report...shot 200 rounds or so
