Yeah, I stumbled onto this stuff a little while back. Shot some of the 115 gr stuff, which did seem to have a bit stouter recoil, perhaps I just didn't notice the flash, or perhaps it was different.

Later, I came across the deal at Buds as they were closing it out; something like $260 for a case of 1450 rds (they put 29 boxes of 50 in it), for the 124 gr stuff. Advertised as sealed case and primers.

I ordered one case, thought about it a bit, and the price dropped about $3 (and Bud's gave me a coupon code too). So I ordered a second case of 1450. As it came out a little under $9 a box of 50, I figured it was as good a deal on brass as I could find, including buying reloads online. I looked into Yavex (the parent Turkish company), and ... their documentation looks legit and good, at least. Appears to be a large company making munitions and explosives, marketing at that corner of the globe. Might not be NATO stamped officially, but the Turks are in a serious hotspot, and I went with the assumption that they weren't making garbage.

I think I can verify- this ammo is indeed, quite good. Outside of flash, it is very consistent, pretty clean, and seems to have a stout load. I wouldn't fret a bit with it in a military (non-HP bullet) role, whether pistol or SMG.
