I'm very surprised with the report on Brux bbls, not doubting the poster in any way but my experience has been extremely positive with them. Been in their shop many times and watched Norm rifle the tubes. He's very meticulous on measuring groove diameter as the rifling is progressing. It also takes a substantial amount of lapping to even open the bore a tenth of a thousandth. Hopefully they got the feedback as their customer service is exceptional. In all bbl manufacturing you can have a stinker for whatever reason and with no questions asked they will make it right. Btw, their little stack of 'returns' is a pittance compared to the numbers they produce. I've picked up a couple of those 'stinkers' to turn into a few AR barrels (.224 and .6.5) and a surprising number of them show burnishing consisting of JB or simichrome after the fact. I cast laps in them to return the bore to the proper finish and they shoot lights out. I'll take a Brux barrel any day.
