H&S,
One of the bulk reloading ammo sellers in this area uses nothing but TAC and CCI450's to fuel all his .223 stuff. I shoot his stuff from time-to-time when the price is right. I've had good luck with his stuff with MOA/subMOA out of several uppers.
As for BLC(2), it's been my experience that guns either love it or hate it behind certain bullets with very little in between.
