Works OK for me with pistol cartridge and 7.62x39 but my AR will break the lip on some trying to extract, doesn't like to feed properly, and I have even had the cases expand and stick in the chamber (cause for extraction issue). It's cheap and steel cases, if it works it works. Don't. Uh a bunch until testing function first.
I have had misfires with both wolf and tulammo. Both were in the very slight percentage. Wolf, 5 out of 10,000 and the Tulammo, 1 out of 2,000. Let me qulaify the misfire. The rounds were a fail to fire. Both companies sent me bags to ship the bad rounds return post and both companies sent me more ammo to cover the issue.
Several (maybe 3 or 4) boxes 9mm at Atterbury through my Glock 17 - 2 FTFs (both struck twice, and nothing...)
Simply won't feed up through my Ruger P95 metal mags. Those steel cases are really rough polished, and my mags are pretty clean. Pretty weird after a mag feed failure, taking out a few cartridges, turning it over and seeing all of the cartridges just jumble up in a mess. I would not describe trying to get all of the rearranged, jammed cartridges out of the mag as, "A good time."
And - it's some dirty, dirty powder.
Upside - a little cheaper than the cheapest at Wang Mart, if they don't have the loose boxed Federal 100rnd boxes in stock. Meh.
I can get decent .223 in 20 rd. box in brass for $6 and change. Why put regular crap gas in your hot rod Camaro....you wouldn't....or would you.....just wrong.
EDIT...steel case runs so dirty. It can not be a good thing.
I have shot lots of Tula 9mm. I haven't had any problems except for several rounds out of one box. Other than that pretty reliable. I saw it at walmart for the first time in months tonight. Very surprised.
