Is all this ammo that people mentioned non-copper-washed? Leadding never the issue in semi-auto causing this?

IMO there's no significant difference in residue from copper washed vs. lead round nose.

[Chaos47]

For the billionth time.. "lead" 22lrs are coated with wax or other coatings.
Pretty much all match ammo is not copper washed.

You said the gun was new, did you clean it before you shot it? If not, that could have been the problem. When a semi starts to stovepipe rounds, its time to check what's wrong, not keep shooting. Glad no one was hurt.

No I did not clean it first. I just wanted to put some rounds through it but I did notice it was real gritty and felt like it got dirty quick. Probably was dirty to begin with.

Note to self: Clean gun first!

Always clean and lube a new gun first. Sometimes they're coated in more of a preservative, not lubricating oil, so they don't really run 100%. Also sometimes you'll get little bits of metal left over from the machining process and it's better to get all that crud out. It doesn't take long to clean a theoretically clean gun - at the minimum field strip it, wipe everything down, be surprised that there's gunk on the towel, relube.

Not gonna say that it caused the issue but..
Yea clean a 795 (and any gun) before you shoot it.
The 795 come with heavy packing oil in them to preserve them. Clean that stuff out before you use it and use a better lubricating oil.

BTW if you have not already check out the 795 Meagthreads

It's happened with my GSG I was using Fed. Bulk stuff...just clean off any debris and inspect then shoot.

same thing with my gsg 5

I had a CMMG .22 upper that did this twice with CCI blazer bulk. Never happened with Federal. Also happened one time with my 10/22 but can't remember what ammo I was using that time. Oh and yes clean your new guns! When I bought my 10/22 I stripped it down to clean it and found a 4" piece of zip tie in the barrel!

had that happen to my 1911 in 9mm blew the back of the case and blew the mag out and all kind of crap back at me

Yep! Good advice for any and all new guns or guns which are new to you!

Had the same thing happen 20 years ago .

I would recommend NEVER putting your left hand around the magwell .

I still have the piece of brass that blew out , in my left palm / wrist area from that day . And the empty case that shows the size of brass in my hand .

I have never put my hand any where near the magwell again .

^^This!

Here's my 17HMR kaboom in a Razor Magnum. I am SO glad my hand/arm was not under the magwell. It would have been a trip to the ER for sure.

Just blew the mag out of the magwell into a shower of bits and pieces. Scared h3ll out of me!
