Doverham: I've posted several times on Shotgun World the offer to send $100 to anyone who would send me a section of pattern welded barrel that "unwound like a spring." No takers as yet.

Have also made it clear that no one on the internet can tell someone if a gun or barrel is safe, lest a personal injury lawyer confuse me with an expert
