I get A message that several of you are shooting guns with less than .020 wall thickness, when the thin area is out near the muzzle. I have a 32 in. specialty Grade 20 Ga. Elsie That has .017 and .015 Wall thickness 10 inches back from the muzzle. some previous owner has draw filed the bottoms of the barels to clean up scratches or dings. Then sold the gun to me. I shot the gun on several occasions. then sent the gun to a gunsmith for a loose rib repair. and he informs me that the gun is not safe to shoot due to less than .020 thickness in the barels. After reading this thread I think I will shoot the old Elsie some more. Thanks everyone for the good read.
