Unsafe 20 gauge VHE barrels

[Bruce Day]

So what is the wall thickness ? It’s not uncommon for Parker 20s to have a wall thickness of .020 from the factory.

Are you saying that only a qualified gun smith can or would have a wall thickness gauge? That is odd because I know that quite a few collectors here have those gauges, Julia auction when they sell a gun lists wall thickness, Jay Shachter the gun seller lists wall thickness. Many more people here have a bore diameter gauge by which they can determine if barrels have been honed excessively beyond standard.

If the barrels are really bad then your options are to get replacement barrels, sleeve the old ones, use subgauge inserts or get rid of the gun.

Have not gotten Delgrego's written evaluation but recall him saying there are some spots with less than .020 thickness. I am not a qualified gunsmith and do have the equipment or knowledge of Parker shotgun barrels to determine if they are safe to shot.
