All Tulammo ive ever shot has been pretty good. I generally try to use brass or aluminum cased ammo but the steel cased stuff is good for just fucking around with. The only problem ive had with it is in my S&W 686 .357 mag. It fires fine but gets stuck in the cylinder. Even if you slam the ejection rod it still wont come out. I guess its just the way the steel expands when fired...
