Agreed. The hardest part about barrelling a Howa is getting the factory barrel OUT. I don't know how big the gorilla is that tightens them, but he knows how to make 'em tight!
FWIW the thread on Howa SA and LA action is 26x1.5mm. A simple metric thread which is almost, but not quite the same as the Remington 700 1&1/16x16tpi (26.9875x1.5875mm).
It looks to me that the Howa MA would have a thread about 22x1.5mm size, coincidentally the same as the Zastava m85. Howa action screws are M6, or 6x1.0mm.
I know the USA has persisted with a love of old imperial measurements, but truthfully it is an awful system and once you work in metric you find it hard to go back. Any modern machining tool will be built to work either way, with most CNC products built to work in metric (with conversion to imperial as necessary). Find a competent gunsmith who speaks metric, even in the USA that shouldn't be impossible.
