I'm looking for a sound percussion double to hunt with, and realize this generally means twist barrels. I am under the impression that Belgian barrels were carefully proofed, and brazed together rather than soldered, and that brazed joints are less likely to weaken and admit corrosion between the ribs. I am under the impression that British barrels weren't always proofed, and that they were generally always soldered, and that soldered joints are more likely over time to loosen and admit corrosion. I also am under the impression that very few American shotgun "makers" actually made the barrels, but that these generally came from Britain or Belgium. Any thoughts, corrections, advice? I realize that some do not believe in shooting twist barrels under any conditions. I am not of that faith.
