I've had two Bear Creek 6.5 Grendel barrels.
neither was a very good experience... the best one might regularly shoot 4 in at 100 m with the same loads my Faxon barrel , PSA uppper and ruger American bolt gun chambered the same all shot said load under moa. and yes I tried many other loads in the Bear Creek barrels but to no avail.
