Five years ago I was using CCI pretty much exclusivley. With intermittent supply I have branched out (Win, Rem, S&B, Fed, even Tula). I am not really noticing any difference in use. (S&B's are cheaper here and just as good so they are my current favorite.) The silvery ones just take a tad more to seat than the brass ones sometimes. Knock wood I have not had a properly seated primer fail to go off. (The ones some idiot ;-0 loaded backwards did not work to well though.)
