I have used 4 if there barrels and had good luck. One was a 257 WB, it would shoot under a dime all day long. I now am working on a 500a2 with a Bauska barrel. They are very cheep in price I only paied $50 dollars (28" 1-14 twist). It is not a barrel that has been air guaged nor hand lapped, but all I have seen seem to shoot well. Phone # 406-752-7706
