Let see right now have Broughton,Shilen,Hart,Bartlein,Krieger,K&P,Lilja,Chanlynn,Lawton and Pac-Nor and I still have one rifle with a McMillian barrel only one not in business today is K&P,McMillian barrels was purchased by Wiseman.
Spence,Schneider,Brux,Benchmark,Rock,H&S,Obermeyer,Gaillard all make nice barrels used some of them in the past.
If you have a rifle build and use a good barrel and you shoot it and your happy with it then it's a good barrel.
I don't select a barrel on cost I look more at how it perform with bullets I want to shoot and I like the idea I get to select twist/rifling/contour/length/bore,groove dia.
