Mr. Hause. As I read your posting I wanted to ask; all shotguns that fail proof in British proof houses would then fail at or very near the chamber, correct? Is there a way to know this for sure? Can it be safely said that any barrel burst further down the barrels must be due to an obstruction or structural defect ie the metal is defective in a significant way? I am really trying to get a handle on this idea that dents are minor bulges are major. Thank you.
