CCI Mini-Mags are the only thing that functions in all of my auto laoders - pistols and rifles. That is what I buy when I can find them. I use Stingers in my bolt guns. I have noticed that quite a few people pitch a fit about Remington Golden Bullets but they do nearly as well in my auto loaders too.
I recently purchased two packages of Federal Auto Match and wish I hadn't. There is nothing 'auto' about them. I wrote Federal about the issues and got no response.
I have tried several off shore brands in recent years because that was what I could find. Generally speaking they leave my firearms really dirty. It has stuck me as odd that foreign makers can supply 22 ammo but domestic stock has been nearly impossible to find.
