ok, some more data...but watt does it mean?

inference here is that it represents pressure specs for post 1954 to 1980 proofed 12 ga guns...

if so, then watt about pre 1954 proof specs...

and watt is a piezo transducer? sounds like a retrofit package to convert your ferrari to a woke hybred...

and if as mc suggests, i am beating this to death, then lets let it go...

and i will just continue to use old ed's 90 - 30 rule when evaluating gun barrels...
