Best barrel manufacturer

Brux,Hart,Krieger,Benchmark is what I have used the most. But being in Canada with importing and availability I've changed to IBI barrels. So far they've been fantastic!
 
How do you have barrels that have never been in an action that shoot ragged holes? I'm a little confused
A little late on the response I bought 4 military barrels from shotgun news that were new still wrapped in cosmoline never barreled up . My dad and I built 4 custom 7x57 mm mausers using those barrels they all shoot lights out.
