chuckle.
I not only have brass likes and dislikes I have them within each caliber.
my 340=A dotes on Remington brass.
my lever rifles seem to prefer Winchester, not just for group size but for extraction too.
I use only Federal cases in my Bergara 0-6 so far, Win in my 03A3, Rem in the 1917 and wife's Savage.
the stag 6-H in 223 shoots best with PMC, but also likes Federal cases when I can find them.
my 7 ICL is a big fan of Remington cases, and the tang safety Ruger [in 7X57] is completely happy with Winchester 257+p cases.
I could go on.
