I picked up a case of Tula back when things started getting crazy, maybe June or July. It was right around when $200 cases of brass became extinct, I came across the Tula for about $160 and said hmmm, maybe better than nothing at all.
Mind you, I have plenty of brass cased, but we all know this year has been funny-feeling regarding ammo.
I've shot some, deciding to use it before dipping into my stash of good stuff. It goes bang fine in my CZ 75, groups decently at 10 yds... good enough for plinking. In my son's P226 DAK, he had a couple light strikes that took a second pull of the trigger, but they all shot fine on that. Guessing the primers are maybe a bit hard.
I've shot a bunch of steel 45 acp and it's all been fine, no concerns about any of it now.
In my ARs and C308 (Cetme), have shot a good bit in 223 and 308 respectively, and again, it's been fine. The Cetme mangles cases anyway.
