Milt, very nice gun. Chain Damascus was usually put on higher graded guns, although I have a F grade L.C. Smith hammergun that has Chain Damascus barrels. I believe someone made a mistake when the barrels were first struck in the white and put into the wrong bin. Since it was already struck and serial numbered to the gun, it was sent sent this way. I doubt that it was special orfered, as the barrels probably cost more than the gun.
In my opinion I believe those reading are acceptable and safe to shoot with your low pressure loads. If you go and look at Doctor Drew's site and look at the pressure readings with different powders it shows that like stated the most important readings are at 9" from the breech. At 15" presssure is dropping and at 20" and up it is less than half.
I always thought it interesting that in some skeet and trap guns, near the muzzle there were holes drilled in the barrels to let off what ever. Maye someone could explain that.
Have fun shooting it, but I still like your 20 ga. L.C. Smith with the 32" barrels. You shoot that very well.
