Well I thought I would add a bit this evening.

My 20ga damascus Flues gun has a thin spot of .018 @ 16" from the breach in the left barrel. I was really apprehensive about shooting it after this discovery, even with low pressure shells.

So, I figured what the heck, I would blow it up or shoot it. Loaded 4ea. hand loads @ 12,500psi per the IMR manual and did the string/proof/behind the tree test. I measured the barrels at a bunch of points before and after.

All is good.
Carry on. ymmv
