CZ 452,BRNO #5 and BRNO #3 heavy barrel.They have far more accuracy potential than guy holding them.I also own a BRNO 21H two trigger 7x57 and a BRNO ZK47 in 30-06 only 20,000 made and they are both one hole shooters.Awesome barrels.......................Harold I also had a Ithaca 72 lever action [Erma]I foolishly sold .By the way Henry is using their tooling.
