Light primer strikes? Barnaul 9mm

[Suther]

Took my FMK 9C1 out to the range again yesterday.

Had a box of barnaul and a box of American Eagle, both in 115 grain.

The American Eagle ran flawlessly. Not a single issue. The barnaul was quite the opposite. Out of a box of 50, 11 rounds were FTF. Here is my collection...

Here is a shot of the bottom...

And finally the AE for reference...

So does this look like light primer strikes?

If not, anyone else have an idea of why the barnaul was so unreliable? I understand its cheap stuff, but I've ran plenty of it through my sks with little to no issues...

The pistol in question is a FMK 9C1 Gen 2, with exactly 188 rounds down the tube (100 AE, 49 blazer brass which had FTE/feed problems(gave one round to a friend for his ammo collection), and 39 barnaul, because 11 didn't go off.) I started with the AE, after two magazines of zero issues, switched to the barnaul, and the issues were rampant (especially on the second round of the magazine - probably just coincidence?) So I switched back to the AE for the rest of the box, again no issues. Figured I might as well finish off the barnaul, hoping it would run better after the AE, and if anything I had even more FTF...

It's the ammo, thicker cups on the primers. I bet they all go off with a second hit.

If you want to shoot alot more barnel then I would look into a heavier firing pin spring. I would drop the barnel though and start reloading.

It doesn't look like a light primer strike; however, military primers are harder and sometimes need a bit more power to ignite reliably. As mentioned earlier you can get a heavier firing pin spring or stick with non-milsurp ammo.

It looks very much like a light strike, the ones in the last picture is once fired American Eagle.

I believe that Barnaul's primers are harder metal, and thus require a stronger pin strike. A few months back a buddy shot 200 rounds of Barnaul in his G17. Had 4 that didn't fire. I put them in my CZ and 3 of the 4 fired. I pulled the trigger 157 times (or so it felt) on the one that wouldn't fire and it WOULD NOT FIRE. So, after that no more Barnaul.

I don't like steel cases anyways, always need to add to the brass collection!

Had the same thing today with a box of S&B 9 124 gr. 2 out of the 50 didn't go bang. My IWI eats anything you feed it but I guess not S&B.

I tired to fire the first one that failed a second time. Still didn't work, so I didn't bother trying the rest.

I dont care about shooting barnaul per say, its a new gun so Im trying a bit of everything to see what it likes. And I am really not sure about whether or not I could get a heavier spring - its not exactly a common gun with a big aftermarket or anything.

As for reloading, its on the to-do list, but I have to move, so money is all tied up for the time being.

The lacquer may have something to do with the fail to fire and it also gums up the gun. I switched to Sellier and Bellot which was only $1.50 more than the Barnaul. Have not had any problems with the S&B but I've been running them through a 92fs and PX4 which eats about anything.

Your picture looks exactly like what I would get with my Glock 17. Clean gun or dirty gun made no differance.
Second hit would light them every time.
The strange part is, Tulammo runs flawless. Barnaul could FTF up to 10 per box.

Just noticed in the first pic that your range really needs a clean up day!
Teach the SKS militia that the big magnet on a stick thingy is actually fun to use.

If the brass lands on the concrete we sweep it up. I can't exactly go across the firing line to get it otherwise... andit looked like that when i joined, so I'm not about to try and pick my cases out of that mess... I assume they occasionally clean it? I dunno I'm new there.
