My step-dad bought some in .45 for his P345 and didn't have good luck with it at all. I bought some in .223 for my Mini 14 and it has shot flawlessly. I don't find it to be overly dirty (although the Mini tends to run very clean no matter what I shoot in it) and I have yet to have a FTF or FTE with it. I bought it at Walmart for about $5 per box of 20 which is as good a price on steel-cased ammo as I've seen online after shipping and what not.
In a reliable rifle, I'd run it all day. In a semi-auto handgun, I'd be leery, but only because I've heard the pistol ammo from Tula is unreliable and dirty.
Hope this helps you out!
