These barrels are a true match-grade barrel, we only have one grade for all of our barrels, our best. All of these barrels are made from 1″ diameter 416 alloy rifle-barrel-quality stainless steel. Every barrel is drilled, reamed and rifled in our shop followed by a stress relieving heat treatment operation. They are then hand- lapped for a superior internal finish and diameter uniformity. With these drop-in barrels we then turn the shank end of the barrel to the proper dimensions and cut a true match chamber.
The barrel is then cut to final length and crowned with an 11 degree target-type crown. Each barrel is then polished to a 600 grit exterior finish and then our name and the cartridge designation is engraved on the barrel. And lastly the finished barrel receives a final inspection and is sealed in a 6 mil poly tube and placed on the shelf.
Accuracy with the Bull barrel and Sundberg taper is excellent.
Drop-in barrels do not require any special gunsmithing. Directions for installing the barrel are furnished with each barrel.
