BRUX Barrels
- Thread starter 30378

I had 2 (back-to-back) bad barrels from Broughton. Nothing against them>>>But it made me part ways with them. So I wanted a "new" barrel>>>I chose Brux. My gunsmith stated he and another gunsmith friend of his had REALLY great luck with 6mm AND 6.5mm Brux barrels. So I "took a chance" and I have been VERY PLEASED with the results. I had mine made into a 6-6.5 x 47 Lapua. I shoot DTAC's and T-Rust me, this rifle shoots within a hairsbreath of shooting just as accurately as my 6mmBR.. So with my VERY limited experience with them, I would recommend a Brux and place them in the company of Krieger and Bartlein barrels>>>very good company to be in!

Use the search on this site, this topic has been covered many times already.
Consensus is that Brux is one of the best.

The following excerpt may explain why Brux barrels show such fine internal quality. James How the Brux Barrels Are Made:
Not being able to visit the plant in Lodi, Wisconsin, I garnered the following information from the Brux website.
For their stainless steel barrels, Brux uses 416R steel that is double stress relieved bar stock. It is 1 and 9/32nds inch in diameter and comes in 20 to 24 foot sections.
After cutting to length, the blank is rough turned in a lathe. Next, it is drilled with a Barnes gun drill by an “oil-through†process. The barrel is drilled at 3600 RPM’s while being flushed with the oil. This drills the barrel to 0.005 inch under “land†diameter at a rate of 1 inch per minute.
The barrel is then thoroughly cleaned and sent back to the lathe to finish the contour of the outside.
After another cleaning, the blank is reamed on a Pratt and Whitney reamer in another “oil-through†process. The 0.005 inch left in the drilling process is reamed away in order to give the proper “land†diameter.
After yet another cleaning, the barrel is lapped to remove any slight tool marks left by the reamer. The barrel is inspected with a borescope and goes no further if it does not meet the strict Brux standards.
After another cleaning, the barrel goes to the rifling machine. In a 4-groove barrel like the one I have, each groove is cut separately. (i.e. Single point rifling) After a small amount is scraped from the first groove, the blank is rotated 90 degrees. After four of these rotations (360 degrees), the rifling cutter head is raised to shave off the next bit of material. This process is repeated over and over until the proper groove diameter is reached.
Once again the barrel is cleaned. After the cleaning, it is given a final lapping. This is to ensure an ultra-smooth bore. The barrel receives another inspection with the borescope before being cleaned and packaged for shipment.
Although many think that premium barrels are overpriced, all one has to do is read the above to dispel that notion.
