Default DAMASCUS-MINIMUM BARREL WALL THICKNESS

What is the absolute least barrel wall thickness you would accept if purchasing and excellent condition Parker 12 gauge DH with damascus barrels??
Thank you for your input!

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.

That is a pretty nice compromise without being too specific. It works for me until we get some more specific measurements from original Parker barrels. By the way, the minimum barrel wall thickness of my #6 frame ten gauge is .100. I feel fairly comfortable shooting the old
2 1/4 ounce copper fours in that one.

IN Excellent condition would you have to question the wall thickness ? Or is this a excellent redone gun ?
