All hand made anything is not going to be perfect, that’s a given. At what point did barrels start to be bored from a solid? It was a long number of years before the US had the technology to stop forming wrought iron around a mandrel. Even the highly advanced French gunmakers had problems holding anything under .040” tolerances on gun barrels. So comparing 260 year old tech against correct DOM metal tube practice is silly.
I do not disagree with the part about being a farb at some point. But to knowingly linger at that part is a failure to do your best. I will always look in pity at those who purposely stagnate themselves.
