I used to use CCI Mini-Mags exclusively, then money got tight. I practiced with Remington bulk and hunted with CCI - until I discovered that two different lots of CCI wasn't igniting all the way in cold weather, and the lack of pressure allowed powder to blow back in my face. It seems that a while back CCI changed their priming compound to be cleaner, but it's not as hot, or I'm given to understand this to be true anyway.
The Remington kept chugging. Sure, there was a misfire once in a while, but it works. As well, Remington seems to use the same lube on their subsonics, so when I use them, I don't have to clean and re-season the barrel for subsonic ammo.
With Remington SS, all shots stay within one hole about half the diameter of a dime at 50 yards. The Golden Bullets stay under a nickel most times.
Regardless, they're both accurate enough from my 'scoped Romanian M69 trainer.
