For the forward 2/3 of the barrels .025" has been suggested as a minimum thickness for safety reasons. The rear 1/3 of the barrels where maximum pressures are exerted requires thicker wall thickness and the wall thickness at the juncture of the chambers and the forcing cone is the most critical as far as wall thickness goes. I'm not certain of this but I think .090" at this location would be about minimum. Others may disagree...

I pretty much agree with Eric and Dean. But I would feel a bit more comfortable with .030 in the tubes and .100 forward of the chamber.

This question seems to keep coming up, so I added the following to the FAQ based on Deans comments.
Opinions welcome!!!! Changes, or even deletion, are options. This one scares me a bit. http://parkerguns.org/pages/faq/BarrelThickness.htm |

Do you numbers change if it is a 10 ga?

Although I have not done it, I think the best way to determine whether a gun is acceptable is to measure the wall thickness of a known original gun of the same gauge, weight, and frame size as the one being considered. The dimensions of the gun being considered shouldn't vary from the known original gun by very much at all. We haven't really discussed what the various wall thicknesses are for Parker composite barrelled guns as they come from the factory. Only when we know what Parker Brothers thought was safe for lightweight composite barrelled gun can we establish a base figure to post on our site.

The gun in question is a very nice one except the barrels have been honed and reblacked.
Right barrel MWT is .027". Left MWT is .022" for about 10 inches rear of choking. I don't think this is a shooter!! Bob Jurewicz |
