we have had much discussion here about minimum acceptable barrel wall thicknesses...

opinions vary...

numbers seem to range from .020 to .030...with location of those measurements rather vague, but mostly some distance down from the muzzles, vs some distance up from the breaches...

but what about measurements up from the breaches?

what in your opinion, are minimum acceptable barrel wall thicknesses up from the breaches and where are those measurements located?

keep it simple and keep it safe...
