doc drew, this is all very nice, but after one inspects the barrels and takes measurements at various points, then what?...

based upon measurements only, what are your guide lines to determine if gun is safe to shoot?...

so far, no one else here seems to be able or willing to answer that question...it does not have to be complex...

unless no one here has enough experience measuring barrel walls to make judgements re suspect barrels...

and you will be happy to know that this is the last time i will ax this question in this thread...

i give up...
